The bug still exists, I checked before I write my first post here. Just don't play annihilation if you don't want to be deceived. The team knows very well about this bug (for years) but they don't care. At the Easter event, I was harmed by the opposite bug. I left the instance but my timer did not stop working. When I found out, 2 hours already had passed. Because of this bug, I ranked 5th instead of 1st, and received 3k instead 8k tokens. This happened 9-10 days before the end of the event and I immediately wrote a ticket (several tickets with a detailed explanation). They had so much time to correct their mistake(or just to add the elapsed time outside the instance), but they just didn't care. They will only care if someone reaches into their pockets. So just DO NOT PLAY annihilation so that there is no revenue for them.
