Creature orientation desync on stun application #31842

Description

Using any stun on a creature resets its facing direction to where it was looking at the end of its last movement spline, ignoring any rotation that happened after it stopped moving.

Expected behaviour

The creature should keep the facing orientation it had after rotating, not revert to the one it had at the end of its last movement spline.
