Event bugs.

Hi . I was pvping in coloseum with my friend underoworld , bloodrush and 2 orcs . Me and under joined a last man standing event . The wvent started i killed some people under did too . And we where down to 3 players and suddenly bloodrush hit me and under full buffed for 5-10k dmg or something . We talked after that . He was not even joined in the event . Just pvping at coloseum . 1st bug.    The other one  was when i joined an event  and one of the guys i had to kill , the last one got disconnected while buffing before gates open . The event started , the gates closed  i waited 10 mins for event to finish . He was my clan mate chaos . He couldnt restart , he crashed l2 window but still nothing happend. No event apiga again .    Furthermore we have to admit that the server not that crowded  so ots realy annoying when i register to an event and loose all buffs even if the event not starting due to low registration.
