MIDI Network callback crashes in multiplayer

I’m trying to make a game for UE4.
My MIDI callback works fine, except when taking it to actual multiplayer
It works perfectly fine in sp.

this section of code is apperently causing the crash.
I tried emptying the implementation for ServerReceiveMIDI, but it still crashed.

managed to work around it by using a class func

Hello Leystyku,

I am encountering the same problem. I would appreciate it very much if you share how did you manage to fix it for multiplayer!

Thank you in advance,
