Guild Wars 2

This is a recurring problem for me and several others who regularly try killing Tequatl:
During the end phase of the event the crash window pops up although everything seems to be fine. Until we get a forced disconnect after roughly 30 seconds that is. (This is actually the most aggravating part of this issue. We would be able to complete the event, but the game cuts us off.)
Sometimes we get lucky and Tequatl dies quick enough to make the event count, so that we can get our rewards after logging back in, but more often than not it robs us of all the rewards for practically contributing 99.9% of the event time. Today Tequatl’s life bar was not even visible anymore when the 30 second timer ran out. I got nothing. Not a single chest for fighting through the whole event but what could have only been the final second.
This is a completely unacceptable situation and needs to be addressed.
