I would suggest to implant the function where bombers can destroy the world and such again. Considering the new lock version called Ownblocks or something that prevents other to manipulate what you have built should block blast damages made by creeps as well. Why do I want this function inserted again? Well thanks to creeps kaboom version vanishing the TNT doesn't work either. And me that have built a creep trap is going to use all this TNT to blast a big cave for slimes... Kind of hard when the function is not working any more.
Please consider this.
