I haven't touched my main world in over two months, but when I tried to log back in, the server crashes as soon as I try to start it up with this error. Poking around a bit, it seems that this error occurs only when I use the server mod "Simple Health Bar" or "API Gem Core". Enabling either of these mods causes this error message. I have many other server mods active on this server running just fine, as well as client mods. Creating new servers with these mods active also results in the same crash, which is peculiar because yesterday I was able to create a server with these mods active no problem. I have tried to do clean reinstalls of DST (deleting both the game files in /steamapps and /DoNotStarveTogether), and this seems to have not fixed anything, other than being able to create a working world with those mods that one single time.
