After hours of brainstorming
and a bad day with bugs on plenty of tables
, I have a great news 
New UNDO system is ready to be tested.
Now UNDO has an infinite depth (nothing is infinite!) but you CAN'T undo:
And even more, if you are playing SOLO, you can cancel all moves: if you don't like a dice roll, cancel it and start over

Almost the whole turn can be started over (there is still a small problem with the supply phase).
To avoid reproducing the problems encountered today, the new system will remain in ALPHA for a few days.
So I need testers on Unconditional Surrender! Alpha that are ready to spam UNDO on solo/duo/trio games.
Enjoy

- red moves
- actions where a dice is rolled (faction determination, combat, airdrop...)
- actions where other player reacts (interception, country setup...)
