I work on command block operated minigames and a big part of them is sound cues played by command blocks with the /playsound command, using this mod (latest version) prevents me from hearing /playsound and I've tried many things to see if I can find out what's causing it, boiled down to this mod. pls fix

Using the following mods:
Xaero's World Map
Xaero's BetterPvP
Dark Loading Screen
Dynamic FPS
Fabric API
FerriteCore
ModMenu
Notes
OptiFabric
OptiFine
Presence Footsteps
ReplayMod

This is an oldie. Curious as to what sound you were trying to play and whether this was on a server.
