First and foremost, if you're reporting a bug, make sure that you post it to our GitHub issues list. Don't worry if you accidentally post a duplicate bug, we'll merge issues where relevant. You can find the issues list here.
Now, when making a thread, please try to provide us with as much of the following as possible:
- Operating system. Be specific if you can, like Windows 10 or Xubuntu 15.04.
- Graphics card. Radeon, Nvidia, Intel? Proprietary or open source (Mesa) drivers?
- Debug information. Did the game give you a message? Can you provide us with a console dump?
- Game version. You can either find this in-game, or in the file name of the universal zip you downloaded.
