MIssle Sillo NPC not updated

Hi, I am aware you are not able to grab the default loot for missle silo NPC, but even updating it with custom items does not apply in-game. Is it currently not supported or am I doing something incorrectly?

I am not aware of any issues with the missile silo npcs. Make sure you edit the right configuration - there is one for the npcs in the silo and one for the npcs on the surface

Can you please double check it then?
I have set both npc's loot to diving mask just to test if it works:



But as you can see the loot is still not changed. It works for any other npc:

Btw I faound the similiar issue here and proposed solution in-fact fixed my problem:

Copying the misslesilo.json and misslesilonvg.json into the data/loottable/default folder made it work

I have no clue why that help, but it did.

Another problem I am having though, is with modifying hte quary rates:


No matter what i add, how i change the amount/work required it stays vanilla and gives +/- 200 stone/tick is this some known issue?
