Since updating this plugin (and with the infinite ammo granted to the player) you are unable to open the turret to place the gun required on the turret !, You will also be unable to choose what ammo for which gun you have equipped the turret with.

I tried revoking the infinite ammo permissions but it still wont "open" the turret to be able to place weapon and ammo in new turrets or replace/add ammo to existing ones.

*edit to last post,
revoked individual permissions as well as group ones so players can  now build turrets but i cannot grant unlimited ammo permission(s)  because of inability to build turrets with that permission granted.
