day of darkness 2 wayy early?

Also a gm posted shortly before the cake was summoned it was about 3 hours and 30 minutes before and you couldnt even see the bomb it just all suddenly exploded and blew people couple feet backwards and stunned them and if it was a hacker it was multi- people cuz it happend to just couple of people that were alone the everyone ran over to get bombed again so it could have been a gm...?

That Run-On Sentence almost made it impossible to decipher what you just said.

Anyway, no, someone just put a bomb down, and since bombs are only seen inside AriantPQ, nobody noticed.
