idk if this is the issue, but when you turn off “evaluatestatemachine” for a humanoid, it just completely breaks even when you turn it back on, however, if you clone it, the clone seems to function just fine.
(123 is a clone of 667 and is completely the same)
maybe roblox servers for whatever reason had it checked off at first???
idk might be related to this (it is a recent update afterall)
omg groovy im ur biggest fan
