Yep, I still got the same bug of her being invisible after the update. I don't know if has anything to do with that NW.js thing that pops up or not.
Oh that? If you are talking about the "Profile Error Occured" error, that is normal. That's common in all RPGM games that are simply older than a prior RPGM game version you have. Here is how to solve that:
1) Go to C:\Users\<Your username>\Appdata\Local
2) Find a folder named nwjs and delete it
3)Go to C:\Users\<Your username>\Appdata\Local\User Data\Default
4) Delete two files named "Web Data" and "Web Data.journal".
After doing all that, relaunch the game and that pop up should disappear. It has a chance to reappear if you play a game that has uses a newer RPGM version so yeah... I've had that problem so many times before.
(If you ask me does that pop up appear when I launch this game, then the answer is no).
