i really liked the addition of customs battles to the game and was trying to use this option. it is still a work in progress. i could only save ai generated deployments as sub directories for later reloading. i think the player and ai have to use the same race. the game crashed too much to check out other oddities.
the custom battles option is very touchy and has to be handled with kid gloves. it frequently crashes. it took down my system eventually. when i recovered the system i found that portions of the gsb2 game were now unaccessible. i removed player created custom scenario files from the main gsb2 data storage file. this did not solve the problems. i then redownloaded gsb2 from gog twice. the access problems still persisted.
finally, i backed up my system from a previous system image, then redownloaded gsb2 from gog again. this action worked. unfortunately, i lost my gsb2 player history and would have to start from the tutorials again, no honors, no challenges, etc. this was quite a letdown for me. i thought i was doing well with gsb2.
a word to the wise, be very careful using custom battles until it is well patched.
Any help will be apprecited.
I didn't find the right solution from the Internet.
