Bug: Place some or all Units, Click Clear Orders (although dunno why this is available prior to Reinforce/Attack, but same thing happens if you have Orders and return to Place prior to clicking Clear Orders), Notice all units placed appear to double where placed (so addition rather than subtraction occurs). Clicking Undo All will then undo the double but still looks as if units are placed although you get them back in your Reserves too and can place again (except Maximums are hit faster since the Player thinks units are already to be placed there). Everything actually re-updates correctly once you go to Reinforce or Attack, so I don't believe anything detrimental happens but potentially confusing display while Placing units.
