Well, what he actually said was "Everything else can be on if you desire as I can build warp openers as fast if not faster than you can and things like mines are only temporary speedbumps." So he's not suggesting no mines as you thought, merely stating that he doesn't care either way.

Clearly though he agreed to no mines, as you suggested them in your next post and his later posts stated that your suggestions were acceptable. But it wouldn't be the first time someone agreed to something in the game settings without clearly reading them or fogetting them later.

You all made mistakes. The question is whether his mistake is somehow worse then your mistake. If not, then the solution to the problem shouldn't punish him exclusivly, as rolling back the turn and destructing all his minefields would do.
