Any brush entity with the texture metal/metalladder001a is duplicated and put in a random spot on the map

[bottiger1]

If you make a brush entity with any face having the texture "metal/metalladder001a", all the other faces get replaced with "tools/toolsinvisibleladder" texture and a copy of the brush is placed at 0 0 0 (in a real map it can be elsewhere) and the duplicate entity is a func_ladder. The original entity doesn't seem to matter as long as it's not just a plain brush.

A brush using toolsinvisibleladder will not exhibit these problems.

The duplication should now be fixed with 1.4.3. The changing of the texture seems to be something that is not preventable (but also shouldn't matter). But I will probably revisit that problem in future again, when I have more time.
