on London I you cannot place anymore anything to the ground (bag, campfire) or build. All building parts you place immediately destroy. I’m not sure if that’s about a hard limit set into the game about entities count. To solve this problem please make all spikes decay faster (there are spikes which are there since 2 weeks at least, never repaired) and don’t allow to place pumpkins too close to each other, so people cannot spam 100 pumpkins in 3x3 area.
This is urgent as none can build anymore.
