After that new update with the continued combat, there's this akward bug. Went pking with a friend and he accidentally attacked me. Then, from that point, whenever i switched weapons(had a seercull and some javelins), my account started to attack my mate. Also didn't get a skull.
Don't know if i can reproduce it, may have been a rare glich.
EDIT: after relog it didn't do that anymore.

Thanks.
