Short description of error
If you have an object with 2 UV's with non-default naming (for example UVMap.001, UVMap instead UVMap, UVMap.001 ), boolean modifier will swap UVs in alphabetical order.

Exact steps for others to reproduce the error

  • Open the file. Note, that the cube has 2 UVs one of them rotated at 45deg.
  • Disable boolean modifier - UV will change.

  • note, if UVs have default order boolean modifier will not swap UVs

I'm not sure if this is the intended behaviour, but it's because the boolean target object also has named UVmaps that don't match, not alphabetical ordering. If you add UVMap.001, UVMap to the white cube in that order, the target UV's won't change over.

Won't mark as closed since like I said I don't know if this is by design.
