I made a model of a wooden bridge, placed it on the map, and indicated the passable cells, but the problem is that when a hero passes through the bridge, they sink to the bottom of the river instead of walking across the bridge.
Most likely, not all the parameters of a "normal" bridge are present in your model – for example, it doesn't know how to react to a hero "stepping" on it.

The editor still keeps giving a runtime error every time!
I know the reason – it started after I replaced a file, as suggested here, to unlock all objects in the editor; I didn't think to save the original file anywhere... Now I don't know how to fix it. Reinstalling the game didn't help (it was also corrupted).
I can only suggest deleting the editor and downloading another one. If I understand correctly what you're talking about.
