This game is playing tricks on me

...i was winning after 2 periods 3-1 and midway trough the third my goalie got injured, score still 3-1, so i replaced him and when i returned to game all of sudden i was losing 3-5

...after game ended in the game report it said that it was actually 3-2 after second and that i just changed my goalies in the third - no injury at all!

(at least one positive thing)...unfortunately no screenshots
I´ve been playing this game for years now and this never happened to me until recently...this is actually second time it happened to me in quite short time...
