Aha thank you for that, I was under an entirely separate impression in my thought process here. Now I get it, so really what should actually happen is a patch applied that removes13B from the listing entirely, as it is only 1 version of that mission which exists.
Otherwise the option is make a copy of 13A and apply minor changes to make a new 13B mission based from that.
So we have a two possible ways to handle this. I've also noted a couple of specific bugs and it may be possible for us to forward the details directly to petroglyph to fix and release a patch for us all. For it to be worthwhile we'll need a good few specific ones as they must go through EA's approval process to implement. You'd know more about this than I do and about many more other details clearly, so I wonder how we can let's say clean a few of these little issues up?
Also randomly wondering if these mission bugs enabled/disabled/inaccessible causes the issue mentioned in "The Best Around Achievement stuck at 80/81 - Tiberian Dawn"
