This does everything except the incrementation. If you defeat a Meltan, `wCandyJarCount` increments by 1, capping at 40. This is represented in-game as 10, going up to 400, simply by adding a 0 at the end. This, in effect, replicates the Meltan quest from Pokemon Go. Once 40/400 is reached, the Candy Jar will become an evolution stone, evolving Meltan. Instead of consuming the Jar, the Candies inside are zeroed out. Currently, the Candy Jar increments, but only once, thus why this is being committed on a separate branch. The bug appears to be at `engine\battle\core.asm`, line 842-861, likely 854-856. It's possible that it could be due to its position in WRAM, or that it's a `db` instead of a `dw`.
