So when I have a pokemon in my party with Flame Body (ex. Slugma), the eggs are supposed to hatch twice as fast according to the wiki. Whenever I'm trying to hatch eggs, it seems as though I still need to walk the max amount of steps for each egg to hatch. It doesn't seem to be working on the server side of things.

Thanks for the report. However, I have been testing this and eggs are consistently hatching in half the time with a Flame Body Pokémon in my party. For some reason /eggsteps aren't going down any faster, but since that's not a command from the mod and is mostly an estimate, as well as the fact that when timed eggs are hatching faster with Flame Body, I'm marking this as unreproducible and closing.
