Crash when tiling a map to itself

[techolous]

The server crashes when a map tiles itself.
The reason I was doing this was to create an infinite hallway.

EDIT:
The crash occurs when an object moves off the edge of the map to itself.
This includes diagonally.

I split the map in two and found this issue:
If you dim door you can run into some problems.
Solved by puting dungeon magic across the map.

I don't think this is really a bug : it's just that map tiling is not meant to do some strange tiling.

I tried many things and every time it crashed (make a sphere, a Moebius ribbon, etc...). You can make an infinte hallway that way :

M1 mapped with M2, M2 mapped with M3, M3 mapped with M4 and M4 mapped with M1, and with sufficiently large (long) map. I think it will work. Test it exetensively though.

But map tiling itself is a useful feature... Think matrix train station.

mlab has a spiral tower, very impressive...
