I managed to bug a Trepor, but this time its a bit different, and I only managed to do it once. Theres a VERY small distance bug, if you stand in the right spot behind the Trepor, then they will not attack and you can attack them. Your AI fix stops NPC\'s attacking a certain range and stops them from moving, then after backing a little further they chase after you, you simply need to line up in the perfect distance where the NPC is froze, but you aren\'t too far away to attack.
Also they seem to use this against me, as I get the too far away too attack message, they are still hitting me, so clearly this fix has made huge distance glitches...
EDIT: Only used this on a Trepor, you could possibly reproduce this bug on other NPC\'s too, but since Trepors are shaped like bugs and have a wide space, its fairly easier to measure the distance point where you can exploit them
