Not really a bug, nor an idea, so wasn't sure where to put this...
But frankly, it seems the price of the Crystalmalizing Chamber is a bit excessive compared to other tools. It just seems a bit high at 2500 currants. Seems like it would be more reasonable to be the price of a fancy pick at 1000 currants or the combo of a fancy pick and smelter at 1700 currants. Especially since you have to buy a grinder and jars for fireflies at 200 each...just to make crystals, it can easily cost over 3500 just for the tools...there are no other skills that are this expensive except for blockmaking which seems to be a more advanced skill anyway. Seems to me that Crystal making should be at most a medium level skill like smelting...and the tool price for the chamber should be more in line with that. Just seems to penalize those that want to start out and work in the swamps...
