According to the rules, joining is prohibited, but on the "Desert_Tournament" map, right at the exit of the castle, there is a single nomad who joins regardless. It seems this was intended by the map creator to make it easier to traverse the sand. If this is the case, then please include all such instances in the rules to avoid misunderstandings.
Thank you in advance.
Also, this map has been reworked so that the hero you choose at the start is guaranteed to become a Knight, because it is impossible to pass by the monk who teaches the "Pathfinding" skill (without which it is simply impossible to play on this map). I might choose a starting hero initially because of the bonuses he provides, with the condition of changing my main hero later. This map does not allow for that, which is incorrect!!! Please either rework the map or revert to the version that was used in the previous tournament!
