God, thank you both so much for this unconditional help. It’s a weird problem, I guess doing it again will be fine. So it isn’t too urgent. Anyway, as I said in a previous post, it would be interesting to know what the problem is to solve it if it happens again in the future. I am using Blender 2.83, maybe it is a bug? I don’t know. Thanks again to both of you for getting involved <3
