It's just as the title says, I have no idea what's wrong
Every other sound effect in the game is fine, I just can't hear a single Pokemon
There really isn't much to say, I downloaded the mod from Reforged.gg, booted it up, and I just can't hear any Pokemon

Heya! I can confirm this is a legit bug - I just had it happen to me as well! I'm not sure what causes it yet - in my case, I've left my game running for several hours, so I'm not sure what triggered it.

I was playing on a testing server and noticed that relogging amazingly did not fix it for me - were you playing Singleplayer, or on a server? Do you remember anything odd happening beforehand? Are you playing with any other mods?

I did some extra testing, and it seems to only occur in Multiplayer, it's completely fine in Singleplayer

And I do have other mods on, but they're all solely Furniture mods, I doubt that would interfere with the sound

Hey, I wanted to provide some information. Running a modpack of multiple mods, me and at least 3 other users have the same issue. Issue is only happening in multiplayer.

What kind of servers are you guys running? Forge, Mohist, other?

Please do go ahead and list all the mods, just in case!

Okay, this sounds like it's just a servers-wide issue, with no triggers, so I'm just gonna chuck this into the Internal tracker and hope the devs can figure it out!

Thank you guys for your patience!
