I created a new dragon shout, all it does is cast 'Transmute mineral ore'
I took the spell 'TranmuteOreMineral' duplicated it, then changed it's type to 'Voice Power'
Then i made a shout with the first and only spell it casts is this transmute spell.
when i teach the word to the player, they must then unlock it. The problem is that when I highlight the dragon shout in my inventory and hit the 'R' key (to unlock the shout by spending a dragon soul) my game crashes to the desktop.
If i use the command 'teachword' and then 'unlockword' it appears in my inventory as unlocked, and I can cast the spell and it works great. But the issue still remains, that If i just happen to highlight my shout in the inventory screen, then hit the 'R' button it will crash to the Desktop.
Just to be thorough I hit the 'R' key on all the dragon shouts in my inventory, no CTD for any shouts but my custom made one

Has anyone encountered this? Any ideas?
