Yes, the error still occurs in the download version. But the console log didn't seem much help at isolating it. I think it happens after the "Day 2" goes across.
I'm also getting several other errors in the console log:
GET chrome-extension://odlameecjipmbmbejkplpemijjgpljce/img/pictures/Nebel_APNG.rpgmvp net::ERR_FILE_NOT_FOUND
GET chrome-extension://odlameecjipmbmbejkplpemijjgpljce/img/pictures/Spider.rpgmvp net::ERR_FILE_NOT_FOUND
Those 2 appear when the game is started.
And after each time that I save the game there's
"Save data too big!"
