One for all and all for one - 2

In such a situation, I would immediately suggest loading an autosave.

As a team captain, I would be against such an action by my player. In our game against Mizrael, both of us faced similar situations, losing not just pawns, but well-developed Necromancers, which could also affect the outcome of the game. We continued playing and learned about it from each other after the match.
Regarding the mod version, I would like more specifics from the organizer: it is being updated quickly, and the "latest stable" version may change ten times during the tournament.
