The issue is that permission blocks are only giving permission to the blocks that they touch immediately around them. This in it of its self is fine, however if the block it touches is apart of say, a door which makes a "door entity", the permission is not given to the other blocks composing the door. The permission is literally given to only the one door block touching the permission block. This makes it hard for others to use a door that was given permissions because they have to find the exact door block that is touching the permission block to open the door. (Shouldn't the permissions be given to the entire door if one block of the door has permissions?)

Steps:
1- Make a 3x3 blast (or plex or glass) door
2- Put a permission block touching only one of the door blocks
3- Have someone either from your faction that does not have rank access to the door try to open it. Or if using public permission someone from outside your faction.

a.) have them try to activate the door while not looking at the exact door block that touches the permission block
b.) have them try to activate the door while looking at the exact door block that touches the permission block
