Was looking at stddef.dm when I noticed something strange:
#define BACK_EASING 6
#define QUAD_EASING 7
#define JUMP_EASING 7
Doesn't seem intended to me?
Might explain some weird animation behaviors we've been seeing @ SS13.
Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? Might be since it was added?
Occurs on 513.1536 and 514.1543
