Boolean - losing UVs after operation, why?

[BenediZ]

Hello,

I'm wondering why I lose my UVs from a boolean operation?

I remember that hasn't been before like that.

Thanks for help!

Ah I see, they were in different UV sets, because the old UVsets did not have standard naming a new one was additionally created...
