Silverpine Forest - Escorting Erland

Current behaviour:

Deathstalker Erland's pathing is erratic. At the beginning of the quest he tries to walk through the wall, fails, turns around and tries again before leaving the house. Afterwards he may sometimes stop moving for a second and when turning will sometimes turn completely around and walk in the opposite direction for a second before turning to the right direction and continuing to walk.

Steps to reproduce the problem:

Start the quest.
