Thank you all for your support

I'm still here and working on this patch, I've been some days out but I had time to continue with my sig shots revision. My plan is to release a new version when I finish reviewing sig shots, and after taking a look at that commentator saying dunk bug, it's very strange, but maybe I've overlooked something. I was working in adding new layups too, I've them ready to be used but the space problem arises again (and I'm still looking on how to edit layup packs to add the new animations in their correspondig pack), as I said before RED MC .iff support could help me with that, but I don't want to make all you wait for this tool to be released, so I will launch a new version when I finish with sig shots and later I'll modify layup packs.
By the way here are some new animations:
A new sig shot for Vince Carter:

The new fadeaway animation for Dirk Nowitzki that was pending:

In the edit player screen he doesn't move his arms when going backwards, but in game it looks as it should:

A new sig shot for Kevin Garnett:

And I've changed John Wall's shooting form:

Plus other edits I don't have preview of right now. Now I will take a look at that commentator bug, I think the jump shot 31 high success rate should be fixed when I changed some parameters that caused a little hitch in the start of the animation, but that commentator problem is really weird...
