Power Gear disabled
I am unable to fire any blaster weapon, then when I tried to kill a spider with an energy sword the spider would only loose half a heart every hit, this is also when I discovered that the power gear isn't working as I was taking more damage then usual and when I tried to fly away the power boots weren't working. Power drills and chainsaws are also broken as the drills do not break blocks as quickly and chainsaws do not cut down the trees. Yes, everything was charged when trying to do these things.
A way to reproduce this is trying to kill a mob with a blaster weapon and energy sword then allow yourself to get hit by the mobs before trying to fly away with the rocket boots. Then also try to mine with a power drill and cut down a tree with a chainsaw.
