HELP please..

I found a real problem in the map file itself.

Inside EuropaSemperV2.3.map, there is a nonstandard embedded custom-monument block named:

:\WeOxide\AP Bridge 2:3830:

Its payload is supposed to be XML for CustomMonumentData, but in your file it is garbled and cut off mid-tag. It starts like this:

<?xml version="1.0"?>
<CustomMonumentData ...>
  ...
  <checksum>cc6a6d023f6252afdef413de8c16bb07</checksum>
  ...
  <fullPath

and then it just ends. There is no completed <fullPath>...</fullPath> tag in that embedded block.

That matters because Rust .map files normally store standard layer data under MapData names like terrain/water/ground/topology, and prefab placement is stored separately as PrefabData. A weird custom MapData entry carrying broken CustomMonumentData is not normal map-layer content.

So the issue is most likely:

this map has broken embedded custom monument / prefab metadata, and RustEdit crashes when it reaches that malformed prefab-related block during “loading prefabs.”

Why I’m confident:

the zip is fine
the .map file is present
you used the password already
the crash happens specifically during prefab load
the file contains a malformed custom-monument payload instead of clean standard map data

This also fits the known Rust mapping failure pattern where invalid or outdated prefab references can break loading. Facepunch’s troubleshooting page specifically calls out missing/invalid prefab references as a common map problem.

So the practical answer is:

What’s wrong

The EuropaSemperV2.3.map file is malformed, specifically in an embedded custom monument block tied to prefab data.

Why RustEdit won’t open it

RustEdit gets to that broken custom monument/prefab section and crashes instead of skipping it.

Is it your two monuments?

No.
Deathray 03.prefab and Enterprise-Badgyver-v-1-0-0.prefab are separate files and are not what is crashing the base map open.

What will fix it

The real fix is to get from the seller/author:

an updated editable map
or an unprotected clean copy
or a version saved after they removed/rebuilt that broken custom monument data

If they have an earlier backup, that one may still open.

Best message to send the map author

You can send this:

Message

Your map EuropaSemperV2.3.map crashes RustEdit during prefab loading. I inspected the file and found a malformed embedded custom monument block named :\WeOxide\AP Bridge 2:3830:. The CustomMonumentData XML appears corrupted/truncated and cuts off at <fullPath. Can you send an updated or clean editable version of the map?

If you want, I can also extract a few more identifiers from that broken block so you can tell the author exactly which monument/plugin section is damaged.

yes

I’m pulling a bit more detail out of that malformed block so you can point the author to the exact monument/plugin section, not just “the map crashes.”

Thought for 11s

I pulled more detail out of the damaged section.

The broken block is this:

Block name: :\WeOxide\AP Bridge 2:3830:
Type inside it: CustomMonumentData
What it looks like: an embedded custom-monument/plugin export, not normal clean map data

What I can identify from the damaged payload:

monument/plugin name appears to be AP Bridge 2
it contains a checksum:
cc6a6d023f6252afdef413de8c16bb07
it includes corrupted XML around monument transform data:
position fields
rotation
scale
uid
farther into the same broken block, I can see at least one referenced asset path beginning with:
assets/.../deployable/elevator...
I can also see entity/config style fields mixed into the same damaged data, including strings like:
entities
input
io/electric/gener...
unlimitedAmmo
peaceKeeper
autoTurretWeapon

That strongly suggests this block is not just a simple monument transform. It looks like a custom monument/plugin serialization containing extra spawned entities and IO objects, and the serialization is corrupted or packed incorrectly.

The important part:

the XML starts like a normal custom monument record
then it becomes binary garbage in the middle of fields
and the <fullPath> area is malformed/truncated

So the most useful thing to tell the author is:

Message

I inspected EuropaSemperV2.3.map and the crash appears tied to a corrupted embedded custom monument block named :\WeOxide\AP Bridge 2:3830:. It contains malformed CustomMonumentData instead of clean map data. The block includes checksum cc6a6d023f6252afdef413de8c16bb07 and seems to reference extra entities/IO objects, including an assets/.../deployable/elevator... path. RustEdit crashes while loading prefabs because this monument/plugin data looks corrupted or improperly serialized. Can you send a clean or rebuilt editable copy without that damaged block?

My best read is:

the damaged section is specifically tied to the custom monument/plugin entry AP Bridge 2
and that is very likely the exact section making RustEdit crash during prefab load

this is my convo with ai. please let me know if any more info is needed. thank you

Good morning

That is a very long chatgpt  conversation , what damaged section ? What exactly are you trying to do and it does not work because it is confusing the whole conversation of above and chatgpt has no knowledge of how Rustedit works to guide you properly therefore the conversation of above is useless
