When placed on a platform, it works fine for me but as soon as I move the platform to another planet, it stops working and it displays "It's charging" but it never ticks up, stopping and not allowing me to fire it ever again. Combine that with the issue of giving back a radar instead of the cannon and I'm forced to waste a ton of resources just because I didn't make it on an orbital platform instead of a moving one.

An orbital ion cannon is installed in orbit of the current planet, as the name says. and that's where it stays.
