Would you please send the music file with the error?

[nin8995]

Would you send a NBT file at world/iammusicplayer/playlist.dat?

[P3rf3ctXZer0]

How would I do that?

Music file (worked fine in single player) https://www.dropbox.com/s/ntl7fvovfgac2ly/%23NL%20-%20Sonic%20Unleashed%20-%20Apotos%20%5BWindmill%20Isle%20Day%5D.mp3?dl=0

[P3rf3ctXZer0]

Even more raw version (Had to zip it though github policy) #NL - Sonic Unleashed - Apotos [Windmill Isle Day].zip

[P3rf3ctXZer0]

Not sure if this helps but I just copied the whole "iammusicplayer" folder and its contents to server after using it in single player.

[P3rf3ctXZer0]

Strange playlist.dat does not exist. Also the folder labeled picture is mislabled as "pictuer" iammusicplayer.zip

This is the zip from the server.

[P3rf3ctXZer0]

playlist.zip

[P3rf3ctXZer0]

I think its a ticking entity bug. NBT looks fine.

[P3rf3ctXZer0]

Another nbt image from a different nbt reader

[MORIMORI0317]

Could not pinpoint the cause. Please delete "playlist.dat" and execute "/worldplaylistreload". If that doesn't work please let us know.

[P3rf3ctXZer0]

I already did that twice.

No Error https://youtu.be/wAxO7T9ZcLk

If you don't mind, can you tell me the OS and specifications that the Minecraft server is running?

We have a test environment only on Windows, so we can not handle it if the error is on another OS.

[P3rf3ctXZer0]

Windows 10

[P3rf3ctXZer0]

The video shows the crash and how I got there even shows my server folder. Do you have a discord so we can solve this more hands on? I have helped many modders with obscure bugs in the past been around since 1.5.2 and I only recently jumped from 1.12.2 to 1.15.2 and I am noticing things are breaking in ways I am not familiar with. I am familiar with cause and effect though. I have the time to test if you do too.

[MORIMORI0317]

I understood the cause, so I will fix it in the next version

[MORIMORI0317]

https://www.curseforge.com/minecraft/mc-mods/iammusicplayer/files/2982273 Released a fixed new version.

[P3rf3ctXZer0]

My issue is on windows not mac or linux will your fix still work?

[MORIMORI0317]

maybe OK. If not, please report it

[P3rf3ctXZer0]

Alright leave this open I will be testing shortly.

[P3rf3ctXZer0]

Seems to work fine now :D
