I'm trying to make stamps of the different gates x AND y x AND not Y x OR y x XOR y They all fit into 4x4 pixel squares, which I've seen a lot of people have difficulty doing. and I've found an interesting glitch. whenever I save them as a stamp, the XOR stops working. so I had the original XOR next to the stamped XOR and guess what? the original worked and the stamped didn't and they were next to eachother sortof, not right next to eachother they had 4 pixels between. the other gates still work. the XOR (the most useful of them all) STOPS WORKING! AAAGH! i'm serious. They were exactly the same. I checked. the particles were all in the same places. and it refused to function. only the right input would work, the left one wouldn't, and both made a signal still. in the original, no signal made no signal, left made one, right made one, both didn't make anything.
