On the subject of potentially stacking status effects incorrectly, I did have a case where I had a Ralts confuse a sleeping Pokemon. I'm not sure if that's supposed to be able to happen or not; the card game handles SE slightly differently and I don't quite remember how the video game SEs stack (admittedly, it's been a while since I played the video games other than just recently picking up Pokemon Essentials and I'm behind a couple of gens so I'm also having to frequently reference Bulbapedia to see how the newer stuff works and what the newer Pokemon are).
The Ralts in question is one customized to have a custom move set (this particular Ralts is one of the starter options so I needed it to stand-alone at level 5 better). It has Shadow Sneak, Sing, Growl, and Quick Attack as the starting moveset, but I had leveled it up and replaced Growl with Confusion. Then later on in a battle (I forget against what, but probably a Rattata or a Furret), I used Sing to put the normal type opponent to sleep and then Confusion to whittle their HP down, and in the process, confused them. The Ralts is also Shiny, just in case that somehow makes a bizarre difference (code can be weird). I can get you more stats about the Ralts if needed.
If that's supposed to happen, then never mind; I'm just being lame. But if not, then I thought you should know.
Also, I haven't finished reading the reported bugs thread yet, so I'm not sure if this is already reported, but while I'm making a post anyway....
I had a weird issue involving Charmander and battle text font size. I had a Charmander (I randomly nicknamed him Spazzler; just the first thing that popped into my head). Whenever I had Spazzler as the active Pokemon in battle and then switched him out for another Pokemon, most of the battle text (such as "Cleffa used Pound!" etc) would often get so tiny that I could barely read it. I have not seen this happen with any other Pokemon yet (but I haven't played around with a big variety yet). And unfortunately, I didn't have that particular game save around long enough to thoroughly document all the factors that might play into it (such as switching from Spazzler to a specific Pokemon), as I had started a "New Game" to test out a feature that took place earlier than my save file, and the game decided to crash and auto-saved, over-writing the file with Spazzler. I don't know if it was his name, species, the combination thereof, or some other factor (like one of his stats or something) that was causing the font size to shrink.
