my colony ships disappear and then reappear on a save reload
Actually currently at this stage ALL my ships started to disappear including once even starbase (after a fight).
Also for some reason there are some specific starbases that can't be repaired with "starbase repair pack" - computer just says "no modules to install" even when starbase has health 4/48 , while other starbase with 42/48 can be repaired just fine.
