Well, since this issue appeared I had already been with the problem for more than a week, I updated to version 3.4 and I was able to reproduce the error when adding lights, although I believe this by default when you use puzzle append, it was to remove it and luckily this one stopped coming out error, I think that in 3.3.1 it was impossible to find a solution but luckily all my work works again and you will be able to test shortly, not to say as soon as I upload or leave it to github as I did in my previous work. But with what I have contributed, no example is necessary, no matter how complex, mine is but without the lights I have been able to get out of trouble, you can always leave lights in the main scene while a fix comes out but with what I have said for sure it will come out fast. Greetings and that everything has a solution soon.
