InvalidOperationException: Sequence contains no matching element

Hi,

We started having this Bolt Compiler error when we try to build the assets. Has anyone ever ran into this problem?

InvalidOperationException: Sequence contains no matching element

We never had this bug before, it ws building allright with our latest changes, and now, suddenly, it compiles wrong.

Thanks
