Haunted House key glitch

[MKSLAYER]

I put some keys in my sacks and i opened a door. I opened my sack and found i still had 45 keys which i had befoer i opened the door. i tried this several times and it does it every time(im using naginata of bile) and it only works for regular keys. sad i am im reporting this but its the right thing to do lol

Doors break when hit enough times.
say /use_keys sack or /usekeys bag or something to have it automatically use keys from your bag as the default
