Lua Error

I have been playing with my friends on their multiplayer server for over 100 days, and have done numerous excursions into the caves without issue. Recently I entered the cave and the game immediately crashed, displaying a LUA error. Now, I am unable to enter the server at all, as it immediately crashes with the same LUA error. (This error exists with the mods on or off.) No other save files have issues with the mods or caves, and no other players on the server (to my knowledge) have run into issues, either. I am playing on steam, but am unable to find the mdmp file, but if you can walk me through it, I'll be happy to provide a copy of that, and/or the server save file, which I have copied from the host to test out on my own.
