So I tried playing again the other night with a friend and we found a couple guns won't work anymore. The only ones we were able to get that didn't work were the Minecraft Crossbow and the Tool Gun (any variety). Did an update to Halo MCC break the mod? Did I do something to my settings? Has anyone else experienced this?

Attempting to fire the crossbow just puts it into the fire position (centers), and then doesn't do anything. Attempting to fire the Tool Gun just results in basically an "out of ammo" sound, despite having 1+ ammo on the counter.
