Whenever GRUNTS and I model interior designs for the dorms in Blood Creek RC3 we keep getting this very bothersome message during compile. There is no way to track it so we can't fix it without knowin WHAT the error is. The following is my tool compile log.

C:\Program Files\Microsoft Games\Halo Custom Edition>tool structure levels\test\
blood_creek blood_creek
Couldn't read map file './toolbeta.map'

couldn't allocate final cluster mirror.

C:\Program Files\Microsoft Games\Halo Custom Edition>

Please help us with the "Could not allocate final cluster mirror.", part.

1) What causes these types of errors

and

2) how does one fix and/or avoid them in the future? Also, what is a "cluster mirror" or "mirror plane" in modeling?

Please help us. Sincere help is greatly appreciated. Thanks.

EDIT: Portals don't have any relevance to this problem. We once removed all portals and it still happened.
