Player PF can grab the key

[GLideKS]

Pretty obvious, can happen these 2 situations:

• if a player grabs the key then that player becomes PF, will still hold the key
• While being player PF, he can just grab the key like any other player does.

My solution suggestion:

• If a player grabs the key, and the player becomes PF, the key should be taken away from him and placed back to it's original position
• for the 2nd scenario, Player PF should not be able to grab the key. only non-pf players.
