Customer service sucks. I haven't been able to train Siege Machines for 2 months. It took them weeks to finally get in touch, but after performing their "fixes", even upgrading the building that makes them, but nothing had changed. Since then, my messages are ignored and deleted. They show absolutely no interest in being of help. The puzzles ARE only a very small part of the game, wholly dependent on upgrading your kerp and the 6 daily ones are just a selection of the same 20 or so in repetition
