Excellent, thanks! I removed the unnecessary lines and changed all the lower cases to uppercases (I also editted the image/saveslot_portraits tex named as "beaker" to "bea") and the character actually appears in the list of characters now, but whenever I try to click on him the game crashes.
Here's the log in case you need it
I found out what was wrong with the textures and I fixed them, now the character actually appears and is able to be chosen, nevertheless when it finishes creating the world the game crashes.

Nevermind, I already fixed it, it just needed a . after sanity xD my bad. Anyway, thank you so so much for your help! I'm glad you stopped by to answer the first post in this thread <3
