this quest ask's you to get 3 crystal chunks from the kaur fractors there are 2 bugs and they wasn't there before the update.
1. the Kaur fractors are not dropping the chunks. i tried killing loads and they drop nothing.
2. before you could try and pick 1 off the Kaur at a time with range attack, but now it doesn't matter if they are not near each other when you attack 1 all 3 come after you. at that lvl you have no chance of killing all 3 without getting killed. this never happened before the update either.
