Summary	08795: sfex2p: Meteo Combo causes a string of unrelated sound clips to play
Description	After a successful hit with Cracker Jack's meteo combo, a series of unrelated sound clips play until the end of the round. (Voice clips like "Round three! playing in the middle of a round)
Steps To Reproduce	Start the game, choose Cracker Jack, fill up all 3 bars meter, then land the meteo combo (qcf+qcf+all 3 kick buttons) without doing enough damage that the round ends, then listen to the sounds. "Oh, no...perfect! Go! Fun..fun...two! Round three! Or, or, round five!"

No.21861 Robbbert Senior Tester Nov 24, 2023, 20:58	I've set it to Direction Needed, which means the devs can decide what to do with this report.
