I like to create small mods for my own use. Recently, I added an “Agile” mutation that adds -10 encumbrance to all body parts (using “encumbrance_always”). In doing so, I discovered two problems:
The encumbrance displays in the character menu (’@’) and armor sort menu (’+’) seem to ignore mutation encumbrance.
Encumbrance can be negative. It should probably have a floor of zero.
FYI: I’m currently using the 64-bit build 8452.
