Sometimes the game gets stuck when cheking mods

Fahrius

title says it all, no much to explain i guess
not always, but sometimes, when checking mods from allies, arena guys or mine, the game just get stuck showing a mod, can't close that window, neither pressing on the red cross or presing outside of the mod window (can't remember if happened with other toons, but it happened a few times when checking darth nihilus mods)
the game is still running, you can hear the music playing, and when pressing the red cross button it glows normally but it does nothing, can't go back
the only solution is closing the game
