Hey man, I don't know how to thank you!

This is my first model and I didn't believe this forum thing would
really work. (I'm new to all this technology thing)
It works!!! Fantastic!!! Sorry...I'm amazed...

Thanks thanks thanks.

Concluding: I would solve this kind of problems if I just turn off
my history button? I tried to clean up things before im my scene like you did but everytime I did this, something important was erased from the Cravo.
