Error reading world data with compactmachines mod on startup in 4.0+ about bluemap

Hey! Thanks for the detailed report, this is a duplicate of #517 .. closing in favour of that issue :)

For this modpack (Direwolf20 1.16) it appears this is the only world where this occurs. All of the other worlds in this level.dat use a simple string here. I do find it odd that this mod shoves this data into the type parameter and changes its type, but this was not an issue prior to the 4.0 rewrite.
