I have set "Allow Players To Deploy A Cupboard": false, - But players are able to place a TC once they have broken it. Is this due to allow players to build overriding it? If I set allow players to build to false, can they still place twig the same as you can if raiding?

mmm, i just tried that to see and idk mine is set the same "Allow Players To Deploy A Cupboard": false, and works as intended even after player builds twig on base (for me this is turned on) "Allow Players To Build": true 
Noticed this is featured is in the/data for each tier. Are they all set to false?
No problems at all on my end, hope you get it all worked out :-)

hi guys, it is likely your Protection Radius is set too low. It should be no less than 50 for most common profiles

Thanks Nivex - My protection radius is set to 50. Not sure what could be, ive looked over all the settings and cant figure it out. Is there anything else that could be conflicting with it?
