Game crushes at the end of a battle

Just before the 3-star Vicroty window should appear, right after the army start to dance, game crushed and closed. No army, no battle in log, no win in stats. Attack was to Rumble opponent.
One more my guildmate reported the same.

 

Has thus happened more than once?

 

Once with me and once with Anrov for now, no more reports from the others yet.
Interesting - 3rd star didn't set, there is no replay and the battle didn't add to Rumble stats being in log:

 

Interesting. Did your bp increase? I'd contact support@rovio.com from inside the game settings. Attach that picture to the email.

 

Nope, I got absolutely nothing. Lost time, donated units and army. That crash was like disconnect for session.

 

Same problem again.
Battle in Log, 2 stars instead of 3, no replay.

 

Sure thing, ma'm. Done

 

3rd crush, just before winning banner, 1 star instead of 3, no replay:

 

Now game crushes at the end of one REPLAY at 4 secs to the end. Right after this moment:
