Blizz, re numbering in meshes:
I'm not keen, for the following reasons:
1. the "blanks" only show up in Arcades level, and then randomly (except one of the Ultron bots, which I've never been anywhere near). If they ALWAYS showed up when my meshes were used, there's some point, but I've seen them show up when using NPCs like Valkyrie, who is an "official" built in mesh, and I've seen the arcade androids happily mimic my meshes. So I doubt my changing my meshes to include the number would help. As ever, I could be wrong. If so, someone please let me know.
2. If your arbitrarily renaming a built in Iron Man mesh causes a problem...errr..don't do it. Leave it as it was and it will work the way it's supposed to. Seems a simpler solution to me.
3. Given that there is still no hard and fast "numbering convention", if I start putting numbers INTO my meshes, then I'm just opening the door to endless "can you re-export *character X* but change his number to the one I've arbitrarily chosen for them, rather than the arbitrarily chosen number you exported them with?" requests, which I don't want.
