So at various points on maps I've had issues with getting my party to actually move to the location I've clicked and other times they move to a location but no longer can move out of it.
I've encountered in a variety of areas in the limited time I've actually played including: The Dark cupboard, Kahanga Palace, and almost all locations in Port Maje (Especially the flooded streets).
I was able to reproduce it when ever I entered an effected location.
However after restarting the game from a save within 'The Dark cupboard' the collision/pathfinding seemed to be working again...
-Operating System is Windows 10
-Here's some screenshots of when I encountered it in the Dark cupboard
