Regarding Diamond – what about one-sided matches? Usually, in VT, it is played without the "One-sided match in a multi-sided match" option checked, and restarts based on the match are usually done in descending order up to 113.
Regarding the time per game, the general principle is: 1 day - 1 match. In case of a delay, there will be a final match. In case of intentional delay, we will come up with something. For example, the opponent will get a couple of extra days to prepare.

And can we enable mob morale in VT?
And can we have stacks appear at the start, like in SoD?
