Not a bug Relearning Tackle

[Viger]

Today, my Charmeleon leveled up to 28. I was expected him to learn fire fang, like he should at that level. But instead, he relearned Tackle. Is fire fang just one of those attacks that hasn't been implemented in yet, or is it something else?

It just hasn't been implemented yet
any move that hasn't been implemented yet is Tackle

Yeah, just like many of the moves that pokemon learn later in evolution like Solarbeam, Fire Fang (and the other fang moves, plus the elemental punch moves), haven't been inplemented in yet. I reckon in the near future (near), all moves will be finished, but there will always be certain bugs to them.
