Some pokémon report the wrong number of candies required for evolve

[just-Addict]

In the channel someone mention Horsey lists as 50 candies required to evolve instead of 25.

On further checking I also found:

Zubat showing as needing 50 instead of 25
Golbat not showing any at all instead of the 100 needed to evolve to Crobat (Gen2)
Seadra also not showing any instead of the 100 needed to evolve to Kingdra (Gen2)
Porygon not showing any instead of the 50 needed to evolve to Porygon2 (Gen2)

There may be others but these are the ones I have and could check.

EDIT: Plucked this from the Discord channel
,sbvakhflsav.fds: dunno if its been mentioned but pokemon that didn't have an evolution before and do now (onix, scyther, porygon, etc.) come up as being max evolution even though they're not anymore, not a major issue, just something worth noting
