Can't proceed further

My first try and first failure, I couldn't proceed any further. When I nocliped to the lower levels, I found a strange glitch with no walls and floors. Please review my video, there is everything I found. 

Hiey! are you using default dungeons? Have you modified them? Walls can disappear if you use noclip, for normal players this should not happen. In order to pass through doors with codelocks, you need to find a code. This code is in a note that drops from some NPCs. There are also some notes in the boxes. Please try again and let me know the results

It was the default dungeon. But it won't work because if I try to put code in it, it says that I'm not on the team with the owner (SimplePvE plugin).

So yeah, if it would work, it has to be zoned, just like raidable bases or other mods of this type. Creating zones using Zone Manager is relatively easy so you can try this.

If the issue is with the SimplePVE plugin, please check the door block from general settings. As far as I know, this can be configured. Also, exclude the possibility of influence from other plugins related to codelocks

Were you able to solve the problem?

For now, no. Plugins designed for players' interactions shouldn't impact it. As I remember correctly from reading assembly, some flags can be set to bases and seen as monuments or something like this.

Sorry. I didn't quite understand what you mean. If you mean the ownerID value for all entities of this event, then it is 0 and this should work fine with PVE plugins. Please, if you have such an opportunity, try to unload the simplePVE plugin and check if the problem is solved. This is necessary to determine for sure which plugin is the problem
