Haven't played through it all yet. But one bug I've noticed, not a game breaking one like the others I've encountered, is that when Psyduck heals with Aqua Ring, if he heals to full health, the text box pops up and says he healed for 0 Health, lol
Other things like my pokemon comign out as invisible in battles, or a wild pokemon not showing up at all so my character sprite gets stuck on screen are things i have to Soft reset for. Thankfully, I haven't encountered any problems with the Save System yet.
Although, I find it strange i cant heal my party with potions outside of battle.
