Crash still occurs in rev.2266 (win-SDL).

I get "tile not empty" error message.

I get the same message for other (occupied) tiles, but for (44,46), the crash definitely happens in my setup with r2266 (pak64: r127 +f+w).

Tested in r2310.
Didn't crash but ...

[edit]
Ahh, this is still dangerous.
If there is a factory or a cityhall at there, we will lost it.
Maybe we might lost savegame.

Why this routine changes the position after checking empty tile.
In this case, checking empty tile is completely meaningless.

Actually there is first a check (Ist_platz_frei()) only then further checks are done. So there is at least on but probably several bugs.
