I posted this same question in the Filefront forums, but I didn't get my answer there, so I thought I'd try here.
I made a fairly big map, and spent 5 or 6 hours on it, only to find out it was too small when I compiled it. I then saved it, deleted the entities, and saved that under a different name. Then I got a new file and loaded the map with no entities (except doors and triggers, do these affect anything?). Next, I used the scaling tool to make it all a bit bigger, but I got this error:
(process:880):Gtk-WARNING(recursed) **: A tag named 'black_foreground' is already in the tag table.
I hit OK
Program: C:\Program Files\GtkRadiant-1.4\GtkRadiant-1.4.0.exe
abnormal program termination
I hit OK again
The instruction at "0x006ba49c" referenced memory at "0x45088000". The memory could not be "read"
Click OK to terminate the program
Guess what I did? I hit OK.
Guess what happened? The program got terminated.
Do I have to remake the whole map or is there some way to fix this?
