What happened?

We made a modded server to mess around in, and later voted to remove the Diet system. But when I delete/disable the mod, the server just refuses to run... Further testing shows that the game crashes immediately the moment a world is created or entered, in multiplayer or offline.
We tried to delete the variable/ID in the crash report (see attached image at the bottom), unfortunately it restores itself upon launching the server.
The full crash report has nothing about the issue except this:
