Small fixes

-Fixed the MapMerge files.
Anyone mapping or planning on mapping needs to use this. Otherwise, please shove a cactus up the appropriate orifice(s).


-Fixed the toxins mixing room.
No longer unsimulated walls. Simply put reinforced walls, renamed to reinforced Fire-resistant walls. With the desc "Blablabla. This one has a special fire-resistant coating."
Simply edited the fire resist temp var from 6000 to 999999999. Didn't want to test if #INF worked.
