Mapmaking tips.

Sometimes, errors occur that are less related to the game itself and more likely to be specific to a particular game session (or, more precisely, a particular map). For example, I once completed the "Axis of Time" map without any issues. However, when I decided to play it again, it would suddenly end in the middle of the game and declare my victory, even though I was still far from achieving it. Perhaps the map was from a different build, but I encountered similar problems a long time ago. For example, in the fourth campaign, in the map about the pirate's daughter, the game would suddenly freeze in the middle of the battle (with a behemoth walking sideways across the bridge in mid-air). I don't remember if I had to replay only that map or start the entire campaign from the beginning – I wasn't making regular saves back then.
In general, I was prompted to write all this by two recent games: "World Museum," where a problem I noted in point 7 occurred after a difficult battle just before the final victory, and "Two Heroes," which has problems noted in points 5 and 7 (the latter problem doesn't affect the gameplay, so the map isn't included in the list).
