Summary: Mending mod is preventing food production objects from completing bills.


Description:

Installed Mending_easymode_0.16.1.0.

Began a fresh colony.

Whenever a colonist attempts to complete a bill on a food production object, the following error log is generated and whatever food item was used or generated by the bill disappears. The Butcher's Table, when the Butcher Creature bill is completed, generates leather/hide/fur, but no meat.

NOTE: There are no unroofed areas within the colony.


Once the initial error occurred, Pawns attempting to perform the Hauling task on food items would become caught in a loop of moving the same items over and over again. This generated the following error log:

When the Mending mod is disabled and the save re-loaded, multiple error logs begin repeatedly occuring:

In an attempt to circumvent potential conflicts with earlier mod versions, the ModsConfig.xml file was deleted and all mods were reloaded fresh. This did not prevent the error from occurring. Disabling Encode's Recycle mod, which has similar functionality to the Mending mod, did not prevent the error from occurring.

NOTE: Upon reproduction of the bug, it seems to only effect production objects that utilize food items, as tailoring, stonecutting, and fabricating prostheses were unaffected and did not generate an error log.

So I'm curious. What is Mending.SpecialThingFilterWorker_Unroofed, and why is it currently bugging out my colony? Or better yet, what steps do I take to fix it? I'm using the latest alpha from Github.
