TripleA tracks bugs in the Github Bug Tracker

The bug report form will prompt you through some standard questions that we need to be able to understand, recreate, and hopefully fix the problem.

If you are not sure the problem you are seeing is an actual bug, or if you want general help, post a question in the 'player-help' category: https://forums.triplea-game.org/category/10/player-help
