Undo problems

[SirDagen]

I accidently clicked on Stonemason when the game started and now I cannot undo it. "/undo" doesn't let me click on the first turn dot, but lets me buy an Expedition, because the clickable area for the even is too big.

"/undo 64" leads to an endless "Pending"-message. I have to resign now.
