Hi, I'm playing the inventions modpack. Made my base, setting up basic power and machines and decided, why not try equivalent exchange 3 Apparently, I did something wrong. I drew 2 transmutation circles on the walls for decoration, but then i couldnt use it anymore to draw circles. It isnt the chalk, I made a new one, but same result. I probably pressed a key, but no idea how to "turn the chalk back on" Could someone help me with this problem?
