What is wrong with mob aggro. I stay far away from mob, i send my summon when he attack, sometimes mob aggroing to me even with so far distance. This situation appears with any mob in server. Is that normal or bug?

Sometimes they aggro on you and suddenly after few hits mobs turn back and go after some guys which are REALLY FAR AWAY...

Maybe geodata problem?

everything is ok. it appears that all mobs and rbs have the passive skill MADNESS (figuratively) that make them for a few seconds attack a random target that is in their aggrolist. after the mob returns to the player that has the most aggro. it's been this way since gracia part 1 i think.
