As I understand how the game is supposed to work, you should be able to fuse THREE level one parts to upgrade to ONE level two part? (And 3 level 2 parts to get 1 level 3 part... etc...) I'm stuck on a mission where I need a level 3 bolt, but no tracks have the option to obtain one (I get the ICON of the character that needs the part on a track that has a level 2 bolt - which I've gotten MANY times already..) So I currently have 33 level 1 bolts, 9 level 2 bolts and 0 level 3 bolts - and no option to fuse any level 1 or 2 bolts to get my needed level 3 part. Am I missing something obvious - or is this a bug? I've deleted the game and re-downloaded and have the same problem, so please don't tell me to try that.
