I am currently playing the Valhesia 3 mod pack and wanted to build something with Chisel and Bits. After sometime trying to build something with my bits, it suddenly just stops working. It acts as if it's not there at all. I can see it, but I can't interact with it. I can't break it, add anything to it, nothing. Restarting seems to work, but that shouldn't be the only solution. I've also tried restarting the chunks but doesn't work either. I haven't changed anything in the mod pack either. Modpack is up to date, and here is the list
