If you experience an in-game (Crossfire 2.0) or portal bug, then please report it to Bugtracker (under Tools in portal Main Menu). Suggestions can be added there. Opening new threads or posting such things on different forums on this new portal is really unnecessary.
For a bug report, add as much detail as you are able. Only saying that "my game has crashed" definitely will not lead to resolving your issue.
Crossfire 1.9 is no longer supported, please download Crossfire 2.0! If you decide for some reason to play Crossfire 1.9, then make sure that the launcher can't load updates, otherwise you'll have this mod version corrupted!
