Water-walking actors evade for no reason
I encountered this issue with Sinnammu Mirpal follower during main quest line.
When she follows player over water, she sometimes tries to evade something as if there is an obstacle in front of her.
This bug happens only with enabled navigator. Note that there is no navmesh for areas covered by water, so maybe there is something wrong with shortcutting.
This bug happens at least on 0.48 and master, did not test a 0.47 yet.
