I wonder if you have ever experience the gluing puzzle when you are making a piece of furniture.
Everything is fitting tight before your glue up. When the glue goes on it's like the timber changes size and it doesn't fit as well as before. Sometimes you could swear you are going crazy. Clamps have to be manipulated at strange angles and occasionally they all have to come off and then go on again. There needs to be a glue invented that doesn't do this. Anybody that could do this would be rich!!!! Don't worry I got the piece glued up and it looks great!
