Line of Warding Bug
I also witnessed the same two players doing it and it seems to be happening on a lot of other servers as well.
Yes there are plenty of waves to move NPC’s, however no this doesn’t cause the bugged skillpoints, infact we’ve actually used this same technique to FIX broken skillpoints.
This could be used to move heart npcs and skillpoint npcs though, even if it does fix them in some cases it can also be used to grief people by moving them.
