If you experience an in-game (Crossfire 2.0) or portal bug, then please report it to Ticketsystem (in portal Main Menu). Suggestions can be added there too. Opening new threads or posting such things on different forums on this new portal is really unnecessary and can be recognised / processed at much slower rate.
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 mod version is now in 2018/2019 the Crossfire ver. 2.0! If you decide for some reason to play older versions, then make sure that the launcher can't load updates, otherwise you'll have this mod version corrupted! Old mod versions are also no longer supported, sorry, we do not have enough resources to do that.
