The only workaround I found to reset the engine automatic pickidle when it glitches and stops working after a script call, conceiled behind a funny sneeze. This is mainly intended as proof of concept for animators and modders in general who suffer of this glitch (i.e. this and others on Nexus).
M/F random sneeze sounds added for fun. The slight graphic glitch during the sneeze seems hardcoded and impossible to be bypassed (not the shake effect, that's an IMOD added by me. I mean the camera flipping 180 degrees very fast for 2 times). Can be invoked in game via X key held for a couple of seconds. Requires NVSE version 4+.
