Would need a bit more info - tModLoader throws this prompt if you try to connect to a server with a mismatched modlist
-> Is the mods handled by our Collection startup option, or manually uploaded?
| If it was manually uploaded, make sure it was added to enabled.json; if it was to the Collection, keep readin ~
-> What mod was added?
| i.e the link to the mod, just so anyone here can check it out; plus if its a mod we gotta fix on the collection system I know which one to go grab haha
-> If you go to the servers Mods path here: /home/container/.local/share/Terraria/tModLoader/Mods is the mod file present via a .tmod file? Is it listed in enabled.json?
| If its missing and you used the Collection sytem, go to .BHCache and delete the file collection_<YourWorkshopCollection>.csv then start the server; should trigger a full reinstall of the mods listed
#the following changes to your enabled mods will be automatically applied if you join this server.
proper notch
If you need help with any of it though, pop in a ticket and we'd be happy to give ya a hand
