This was reported to me by -SuperNova-
apparently, his friend, Fenia, gets 503 exp from lvl 172
but then when they play the level again he she gets different Exp
The Exp flip flops between 503 and 1320 every other game
Fenia is only about lvl 80 or so so the Exp should not be changing at all anyway, let alone alternating between 2 different values every other game.
Please Note: It doesnt have to do with pushing.. I watched and the only one they were pushing was the boss each game.
