Affected Mods:
Vanilla Furniture Expanded, Syulipia Slime, potentially any mod that adds furniture?

The following errors occur if 'prisoner arena' is above furniture mods in loading order. This error repeats for potentially every piece of furniture added.

Config error in Radio_Industrial: has null thingClass.
Config error in Radio_Industrial: has components but it's thingClass is not a ThingWithComps

For some reason this is only logged if rimworld starts in debug mode. Although this doesn't prevent the use of the furniture, It can cause some weird issues with other mods. For example, while loading a save, some objects failed to load in after Doors Expanded threw an exception while running a check on any object mention in the early error log.
