The catch bug happened to me too, where you catch a pokemon and then get an instant encounter that softlocks the game, I just saved everytime I caught anything after that.
Found out that after a battle in the Blooming Forest cave puzzle area, ground items will respawn but only get counted once, you can use them multiple times still and get into negative of that item.
Another bug, if you use Belly Drum your ATK stat will stay boosted outside of battle and carry over to the next until you heal at a tent.
I found some glitches, you can somehow get offset 1/2 a tile and just walk through the boulder objects instead of having to use strength and push them. In Blooming Forest, if you mash through trainer text you can talk to them again and start 3 battles against the same trainer at once.
