Regarding the fourth mission, it's unclear what needs to be done to raise morale. As for the second mission, I would appreciate it if it were more clearly explained at the beginning which dwarves should not be attacked. I protected the local dwarves as if they were my own (I even avoided the first garrison to avoid actions that would be considered aggression), but in the end, a lot of time was wasted. If you play for the first time and don't know when the untouchable fleet appears, it's unlikely that you'll be able to complete the diplomatic condition because: 1. The super-dwarves are rushing towards the cities, 2. Judging by how quickly they catch up, their logistics are improved. In my opinion, the condition can only be fulfilled if you don't take the last elven Castle (put a second hero as a decoy to guard it). That is, so that they don't appear at all by the end of the mission. But at the beginning of the game, there is not enough information to plan like that. Maybe these dwarves should have a ban on attacking cities; then it would really make sense to run away from them – in the open field, they are very strong, and/or their logistics should not be improved?

There was also an annoying but convenient bug in the game. At a certain point, when the fleet had been defeated repeatedly, the dwarves froze. I didn't touch them; they stood still and didn't move. But at the same time, the brown player's turn lasted about 4-5 minutes.
