@Vladimir, please check the slots in your mod. These cause problems with other mods. E.g. with the RAG_Cabin mod, https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=2988726228&searchtext=rag+cabin. After the last RusForma update, you can no longer enter tree trunks in the foundation. The developer of the Cabin Mod has shared this!
This happens when you run a mod which is overriding slots the wrong way.
