Thanks for clarify my doubts, so i think i can't buy the animals because i have this quest from billy, and can't make rope because the recipe is missing, well as you said "it was disabled for some reason". Thanks anyway.

Version 0.40.2 , which I uploaded few hours ago, should fix all of that. Download it, overwrite your old version and your old saves should work fine and those problems should be fixed. Billy will start selling animals and you should get the rope recipe, together with the working fridge and other fixes.
As for the suit, there are other outfits that work like you proposed. You can't wear them if you are too young. I just never got around doing the same for the bunnysuit, plus the sprites are already in the game. In the future, the suit will be most likely removed and it will stay as a reward outfit for finishing the game in certain way.
