I apologise for the inconvenience, the original .zip of the Flashbangs 
only had a backup globals.globals, not one that uses the flahbangs. all 
should be well with this one. Remember : BACK UP YOU ORIGINAL FILES.
This also has an item collection for the Flashbangs, if you don't know 
how to make one. If there's anything still missing or messed up, PM me at 
gearbox and I can fix it - Though I'm pretty sure that this is all that I
left out by accident.
