-Yeah found out the reason, pretty clear by logic after figuring it out, but still somehow functional for normal species apparently(itjustworks.jpg)???
-The stuff was relying on some sort of "descriptor" in the has_limbs list that does not seem to even exist.
-Adding this "descriptor" to custom species limbs list reliably fixed the issue on test runs.
-No fucking clue how the other species somehow manage without that thing however.
