If you name a craft "_something" you won't be able to see that craft in the crafts list, but if you search something in the searchbar then it appears
EDIT: I'm regreting this bug report because now I see the possibilities of hiding the crafts, my list is too long. But I'm sure that the possibility of creating folders of crafts is a much better solution, so I'm going to keep it up
EDIT2: Points are also problematic, maybe the game shouldn't allow the names to have those characters
Edit: forget what I said, it lets the player save crafts with all chars, it was a bug preventing me from saving any craft
@AndrewGarrison so it looks like this is fixed now, when you use - . _ or similar chars it doesn't allow you to save a craft, but it should warn the player about what is causing it to fail.
And btw, I think there's a bug related to this but I have to test it more that causes the save craft option to stop working after entering numbers and points
