HoMM3 HD bug reports.

Let me explain what a map drawing error is. If a critical error occurs during map rendering, HD, unlike the original, doesn't crash but simply interrupts the map rendering and allows you to save the game. A critical error during map rendering occurs as a result of a map bug (which usually manifests not only during rendering, and then a crash occurs). After you see a map drawing error, saving the game will record the map bug that caused the error. In theory, this save can be fixed and the game can be continued normally. But fixing it is time-consuming, and no one is going to do it. In general, if you see a map drawing error, you need to load earlier saves until you find a healthy one.
