As of recently, player seem to not be effected by zone flags. People can paint on signs, killsleepers flag is not working properly, undestructable arenas somehow seem to have holes in them etc.

hey, here the same, flags nopickup and no entityPickup dosent work.

Yes! I confirm that the flags are not working correctly. For example, you can not remove the combination lock, but easily removed lamps and garlands, door closers ..
It is necessary to correct. And then the objects are only so stolen

also "nostability" isn't working

I can confirm also, flags not working.

NoEntityPickup flag is not working for me, Is anyone else having trouble with this?

change on line 465 this

private object CanPickupEntity(BaseCombatEntity entity, BasePlayer player) => CanPickupInternal(player, ZoneFlags.NoEntityPickup);​

to this

private object CanPickupEntity(BasePlayer player, BaseCombatEntity entity) => CanPickupInternal(player, ZoneFlags.NoEntityPickup);​

it works for me

NoBuild is not working for me please help radiation is working but all other flags arent

if u have owner /auth. lvl 2 Status then u can build. u need a player to try build and look if it works.

yeah we tried still did not work
