ForceSneak behaviour is inconsistent if the target has AiWander package
If you use ForceSneak on a NPC, their arms are stuck straight down to their sides, which looks weird. This is with "ForceSneak", a script toggle rather than the animation functions (PlayGroup and LoopGroup) but #3895 (closed) may be related.
