Inside the config for gear_food.pbo, under the Worm class' Health class, starting from line 9538: "DZ\gear\food\data\"""".rvmat" has four " in the middle, this happens five times, at lines: 9538, 9546, 9554, 9562 and 9570.

This error makes the rest of the Worm-class, as well as the following ~2800 lines of code appear "commented out", or rather placed as text instead of being actual code.

Changing

DZ\gear\food\data\""""

to

DZ\gear\food\data\

fixes the problem.
