When MF received the Love Tap passive, her Arcade skin got an awesome sound effect to match. As you can see in the Skin Spotlights video, there were two sounds, a primary and an alternate. First blip, then bloop. As of 5.23 (I think), however, there is only one sound. First blip, then...blip. You can hear this here: https://youtu.be/9GuzkKp7xqs
How to reproduce this bug:
Riotmoonstones3 votesHeyo!
Thanks for the report! This is a known issue and we're working to resolve it!
iHerring1 votes5.24 update, some brief custom tests revealed the following
Blip bloop vs blip blip - blip blip still remains, no bloops Arcade MF vs classic MF - still plays the classic MF auto attack sounds Arcade MF vs Caitlyn - no longer plays the Caitlyn Q sound on triggering love tap. All glory to KateyKhaos.
Riotmoonstones1 votesThank you for the update! Lemme see what's up with the rest of these! Also, Happy Snowdown! ^-^
Anihaku2 votesI hope they didn't do this on purpose. The fact that they added those SFX to that skin made me love it even more. Sad day if that doesn't get fixed :'(
EDIT: Now the sound of blip....bloop is playing on repeat in my head xD
Deal With It2 votesConfirmed. Miss Fortune needs the blip, then the bloop. Not two blips. Blip then blip just doesn't work.
As a kind riot employee suggested, I would also consider a blip then a blop (vs a bloop). But they can't be the same.
Thanks
iHerring2 votesReblip the bloop!
I had noticed this as well but I figured it was part of the ongoing Arcade vs regular MF and Arcade MF vs Cait SFX bugs. Have these been fixed? I don't get to play MF much so it's even rarer that I go MF into MF or MF into Cait.
EDIT: then I remembered custom games were a thing. Can confirm that Arcade MF still has both those SFX bugs, frowny face.

I think you meant to say reBLOOP the blip. The bug is two blips instead of 1 blip and 1 bloop.
iHerring2 votesI did consider that, but blip -> bloop sounded better in my head.
Deal With It3 votesBut make the noise aloud. Like in-game, bloop is superior to blip.
iHerring3 votesExactly, that's why I put it 2nd. Whilst technically reversed, it felt much more pleasing to finish with a bloop instead of a blip.
Deal With It3 votesBut understand that there currently is no 'bloop' to rebliip.
iHerring3 votesI hadn't considered that however. You've given me a lot to think about.
Deal With It3 votesI hope I've done the same for Riot as well. Perhaps they'll conclude (and agree) that the bug is obviously critical to gameplay and will schedule a hotfix accordingly.
iHerring3 votesI'm starting to think that Arcade MF players should be given a compensation skin for all this hardship. It's been what, since 5.23 the SFXs went bad? I'm starting to get the shakes whenever I play MF without proper sounds.
Deal With It3 votesYou've given me a lot to think about. I didn't realize how much hardship I've experienced as a result from this major oversight. I'm thinking about starting a support group for others like myself.
iHerring2 votesHi I'm iHerring.
Hiiii iHerring
It's been about 2 patches since I last heard the proper Arcade MF sounds.
Supportive, gentle murmuring
I just got out of a game and... and... there was no other MF or Caitlyn but I... -sniff- still didn't have the sounds... I'm sorry I need to step outside a moment.
Gentle murmuring intensifies
TheHoodsmen1 votesThis is a still a problem for me 
i miss hearing the cool sounds. Is there anyway it could be fixed soon? Every patch i try to see if it is fixed in the bugs sections but is never there RIP
