I was at this match.
Yuliana got a code violation for unsportsman like conduct in the 3rd set at 30-40 then she double faulted & lost her serve. The warning was complete crap the umpire said she hit the ball at the linesman,she didn't. Also after the 2nd set Putchkova took a long toilet break then had the trainer she was clearly struggling in the heat, it took maybe 15 minutes.
Perebynis was there supporting her
Good luck to Yuliana for dubs & the rest of the season
