A couple more minor issues I've found:
Cursola and Runerigus both do not have a box sprite.
I haven't been able to find the Grookey egg in Chrysolia Forest. I don't think I've overlooked it, but could you tell me where it's supposed to be?
Titanice doesn't appear to spawn in the dive areas of Azurine Lake. I've checked each of the dive zones with a Magnetic lure, both inside houses and in the main areas. Does it have a specific section I may have missed it's supposed to pop up in?
Really small, but Harylect appears to spawn in Neo-Berryl Ward, not in Neo-Rhodochrine Jungle or Neo-Malcheous Forest, contray to what the guide says.
Otherwise, all of the other Pokémon, aside from the bulk of the new legendarys (I haven't gotten that far yet lol), appear to all be obtainable in a manner that is balanced with the progression of the game. Nucleon does tend to absolutely wreck house when it gets the chance, and being able to get Seikamater before the E4 seems.... powerful. But I haven't tried it against them quite yet.
Even with these minor issues, I am absolutely loving the mod. Thank you for keeping it going! :)
