i've had this problem as well. i followed the directories on both the client and server sides to delete the interiorshared.lua file. but i've not been able to enter any of the RVs

Hi! That file should be called "RV_Interior/media/lua/shared/rvInteriorShared.lua", with that capitalization. Linux has a case-sensitive filesystem, so I'm not sure it ended up with the wrong capitalization of the filename like that. It should also start with "rv".

You could try manually correcting the filename on your server and see if it helps, or perhaps delete the existing mod files and get your server to re-download them.

Recently having this issue on my server, not using Linux, hosted on GPortal. Was there a solid fix for this yet by chance? I've tried renaming files, i've done a full server reset, not sure what I'm doing wrong here.
