The 0.13 mods seem to be missing their moves.
As far as I know the vt+ mod does not exist for .13, which is what you need to have in order to enable the modded characters to have skills. If you do have a vt+ mod equivalent for 0.13, then the skills should be present, as in the class files for the characters they have their abilities just like they do in the 0.12 versions. The only fix for this is for me to get into the code and configure it so that it reads in those abilities, or for the other guys to update their vt+ mod for 0.13. If you do have the vt+ mod for 0.13 and the mods still don't work then its black magic.
