Snufkin, I am using this with SMX which modifies user interface so it may interfere with this mod. In previous version of your mod, its UI was not centered on the screen for me, it was pushed more to the left side, but the mod still worked without game breaking issues. In this version of your mod, its UI seems to be centered on the screen, but there seems to be a new issue which randomly moves the output slots (from which you grab the coins) to the left side of the screen so much that the bigger part of it is outside of the viewport. For me this part of its UI by default is not placed perfectly at the same spot like we can see in your screenshots, but it's still useable, but only temporarily until it moves to the left outside of the visible area (fixed only by reloading the world). I suspect it also somehow interferes with another mod which I have installed called Custom perks v2.02 (updated from v2.01 at the same time of updating your mod), more specifically its SMX patch which is simply there for compatibility with SMX and what happens there is basically that couple of perk icons are slightly shifted to the left. I'm not sure if this has anything to do with the shifting problem that I am experiencing when I use your Slot mod, but I thought it would be worth noting as it exhibits a similar behavior.
