I wanted to make a gripe list about the editor in hopes that someone has found a work around for one of these. Here goes:
Strange annoying bugs in the editor, can anyone explain these?1. Sometimes after many hours of editing a map will start to crash after a few minutes of editing

. I had luck fixing this once by copying the files into a new mod folder, but that did not work with my latest file.
2. While editing my cave map, I placed a few dungeon passage props, upon reload a third of the map had sunk to 1 meter and was painted straight black, if I tried to raise and recolor it, the terrain would revert back to low and black upon reload.
3. Inverted props (espcially valley_rock_flat) will sometimes disappear entirely
upon save.
4. Sometimes clicking outside of the minimized editor window will cause the screen to go black and the whole program to seize up for minutes at a time.
5. Random teleporting of players to the top of maps. (I am still unsure at the cause of this)
6. Players popping' up from under a bridge model instead of hitting their heads on the underside, even when downwards facing blocking is provided.
7. Staircase models (especially the dungeon_tower) causing players to move jerkily up and down them, forcing manual ramp blocking.
8. Patches of ground texture becoming see-through
