This was the solomons AH3 map? Both the CBM and strat map are BMP files so the numbers can not actually be changed by the program / code. I just took a look at the AH3 strat map and loaded solomons in a custom arena and the base A11 is at 12,9,1 on both. I just checked the strat map over on Ahevents.net and it is correctly marked there to.
Base A46 is over at 6,4,4
So was it your CBM map that was screwed up? Or a map sent to you via email?
P.S. I am the creator of that terrain.
