All,
I alluded to this earlier that this update would be a long and bumpy journey. Unfortunately I found out that currently you are not able to create your own plane sets in the new version. This has to do with how double quotes are used in some fields.
I just fixed it in the code, and will release a hot-fix in not too long. If you really want to create your sets right now and you are having problems you can fix it by doing some mass text substitution.
Say you are in the UQMG "ini\BAT_WAW\main\RandomSets" folder. A custom Randomize file you create would be named something like "rnd_set10000.ini" (Custom files are always named from 10000 and higher).
A typical line would look like this:
(F) Curtiss P-40B, 1941,notused,[ru] <USSR>,1
But because I use the text that comes from BAT, I have to deal with commas in comma separated text fields.
To properly work, this field would have to be edited to (note the double quotes):
"(F) Curtiss P-40B, 1941",notused,[ru] <USSR>,1
The best way to do a mass text substitution would be to substitute all occurrences of {,notused,} with {",notused,}, and then add a double quote to as the first character in every line.
Really sorry about this.
