See the report http://11x11.fr/reports/46113315 where my players gain xp 2 times.
the reason is alibashi comes in play at 59mn when an other player injure, then at 81mn alibashi injuried too he was replaced by marsin'u.
if u look at report alibashi apears 2 time in xp and marsin'u didnt :
Lf [Remplacement] 59' Matija Alibashi [Blessure] 5.4 120
Lf[Remplacement] 59' Matija Alibashi [Blessure]5.00 11
An other things it was a 500%xp tournament and i think xp win by all player was very low too. with same win and same player and same player note i win 2 times more xp match before and match after
i hope this ll help u, and sorry for my english
