Hi, first of all congratulations for this great game - I am in love.
In our 8-player game, we are having issues in cancelling future timewheel orders. the case seems to arouse especially if there is just one future order left or if there is a specialist movement scheduled.
Thanks,

Try using the "Contact Us" form within your specific game. It automatically gives them information about the game in progress (game ID, game state, variables, etc.). Be sure to be specific about who's tried to cancel future timewheel orders, and what orders won't cancel.

Agreed, I pick the future order select cancel, it disappears for a moment and then reinstates the order

I believe this is already on the bug list and has been fixed in the next release. It's a pretty rare bug though, I've only seen it twice, and in one case, it went away when I cancelled different orders.

I had this happen as well in a game that's still active and although I don't have the exact tick, I can show where and when it occurred if need be.
