I think you should understand that a blocked mine is not a reason for a restart on any map. There is no connection between restarts and mines at all.
A restart due to a block is given only in the case where there is absolutely no way to leave the castle and turns need to be skipped. If there is another way out through rough terrain, then this is a normal game situation. There are restarts for this.

A block on the only road is a restart. The limit for the duration of a block is 112. If you see a unit on the only road, and defeating it will result in the death of the army or more, then this is a block, and therefore a reason to inform the opponent about a possible restart due to the block (while you yourself cannot check and attack the unit - you need to send a save to the tournament judge).
And there was a question asked above, I will join. Why is the old AC composition still listed in the tournament rules thread? Who is actually on the new AC? Who can I contact in controversial situations? If the respected judges are not too busy, please answer.
