HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

[ ] if the host is using HD mod beta 8 + Tournament Module enabled, then a client without HD mod beta 9 + Tournament Module will not be able to connect; both will receive a notification. The reverse is possible: HD mod beta 9 + Tournament Module enabled connects as a client to any version 3.2/4.0, but in this case, the game follows the host's rules.

Am I correct in understanding that if the opponent does not have the corresponding version of the mod with the Tournament Module enabled, then none of the Tournament Module functions will be available to either of us?
If so, perhaps it would make sense to move from the Tournament Module to the General module those functions that do not give an advantage over the opponent and that can be agreed upon with him, for example, healing of silver/gold units, choosing paths, building a second-level structure (if it will be available), etc.?
Otherwise, it turns out that the transition from 2.9 to 3.0 is associated with the loss, in many cases, of the ability to use very important (at least for me) functions of the mod.
