Something did this and unexpectedly removed this?

"Something unexpectedly tried to set the parent of ChunkB1 to NULL while trying to set the parent of ChunkB1. Current parent is Camera."

This is the only part of the script that does parent this thing only, The rest of the script is unimportant

After it says that message I find the chunks that I tried to load as empty models with only scripts and etc and no parts, This is infact confusing me really bad, I would really like some help
