Valeria's blob can obstruct Kuzmann's electricity beam (at least on PlayStation 4).
For example, one time my Kuzmann's beam was being intermittently stopped by the Valeria's blob spam as we took down the extract barrier together on A Low Blow. It did not come across as a bug per se, but felt off. If you're on the same team and are trying to stack up on damage such as the way mentioned, you might be affected. Valeria didn't seem to have problems.
Also, I am curious to know when Kuzmann and Valeria are face to face in a PVP context, if Kuzmann's beam will still be canceled out by the big blob.
