Hello. There is a town in my server which is mostly made out of snow and ice. Recently there was an issue where a player went to the city with a pumpkin in his hand, placing it to the ground to get rid of the snow blocks. Because my server has WorldGuard, he was able to basically place the pumpkin in the ground and then WorldGuard blocks him from placing it and he gets it back directly to his inventory. No snowmans will spawn because the mob-spawning is denied in every single town I have in the server. Is there any solution to this to stop this from happening? So that after pumpkin is placed on top of 2 snowblocks, it wouldn't spawn snowman?
