save breaking bug

i usually have to wait untill the relm im in resets to get back in. Im currently in act 2, and it contains the following text.

Attempted to resume pathing action with an invalid skill: 1073741824
object: Metadata/Monsters/EtchedBeetleArmoured@32

i can no longer open my save as i was in the hub for act 2 when the bug happened, I am playing a witch with the Lich ascendency, and was on the vally of titans the first time it happened.
