While using a controller on monoliths (never saw it during campaign) I found that moving during channeling attacks (warpath) caused my character to sometimes seem like they were sticking on the map and didn’t allow my character to move much at all. It would almost feel like lag, but it was happening real-time. It only took effect during moving while channeling and persisted throughout the entire monolith.
I found that if I used a mouse and moved around it would cause this bug to fix itself for the rest of the map/monolith without issue. Not until next game restart only map restart, though.
