About an hour or so ago I picked up my old pokemon red game and started playing it again however I noticed that when I evolve my Weedle into Kakuna at level 7 its not learning harden. Im training it just left of the second city in the game outside of the elite four area if that makes a difference. Has anyone else had this problem and if so is there anyway to resolve it? I saved it right before he turned into Kakuna and evolved it three times and each time it did not learn harden. Two of those times I evolved it to level 8 to see if it would learn harden then and it did not.
