@Uveso Thank you for dropping in.
I've closed the issue in question - the default unit cap remains 1000. With a recent PR introduced by Askaholic and Blackyps we can now dynamically set the game options with the server. There we can inflate this number as required for ladder, without affecting the test setup of the AI developers. This will be available when TMM 3v3 / 4v4 is, and that shouldn't be too far out anymore.
