The second was that whilst we were placing our troops, the game would also be placing them somewhere else. (NOTE: It was manual)
Thirdly, when we/it had finished placing our troops, all placed troops would disappear and the regions would go back to whatever they were before, in this case 1s.
Finally, it would end our turns halfway through, with the region that was selected when the turn ended still being highlighted.
They are the only ones we discovered, as we decided that there was no point in playing on and so drew.
P.S: The bit in the top right of the screenshot is my special screenshotting software. Normally that hides itself when you select one, but it didn't this time, no idea why.
