Due to the way that photon batteries are crafted (in stacks of 100) they are able to be exploited in combination with the Industrial Grinder. Just take a single stack of photon batteries, put it in the Industrial Grinder, then grind them 20 at a time. You will end up with far far more mats than it costed to make the original stack. You can then use those new mats to make more stacks and regrind them indefinitely. Essentially you can have infinite polymer, crystal, angler gel, and oil. Is there some way you can redesign the ammo to fix this exploit so that photon turrets will be compatible with the Industrial Grinder?
