This game is really neat! I know it's an early release, but deleting objects is pretty hard, and sometimes marked buildings will cause them to keep trying to build it, draining every bit of alloy, while not allowing it to be deleted. I think the glitch was caused when I marked a turret for deletion while it was being attacked and destroyed.
Thanks so much for giving it a try!
I know that delete can be glitchy and wonky right now and am working on fixes for the next patch :)
I'm also working on a simple slider that will allow you to better control the drones so that they don't instantly drain your economy by building a bunch of stuff while neglecting mining.
