There is a glitch at the moment where people can somehow store a watchtower inside of a wooden crate, I'm not sure how they do it. But once they have it you can place the wooden crate, shoot it until ruined and the whole watchtower will appear. Goes inside walls,buildings, and pretty much anything. The other issue with this glitch is that they are being stored on character accounts, so even if the watchtower-crate glitch gets fixed people can just duplicate more and we are back to square one.
People are getting crazy with it and just spawning watchtowers everywhere and making servers very laggy, and it just doesn't look nice. Please fix this !
