Here's a bug that I kept forgetting to include in the reports:
For a while now, and up until the last version, including (haven't tested in the current version yet), I noticed that if I had control groups from previous maps, they would not clear for a new map. This results in me pressing 2 or 3 and selecting a random group of units and structures, including some that were not even mine, if I had not assigned a new group 2 or 3 yet.
