Version: 1.1.5 - 1.20.4
Loader: Fabric

I just updated to version 1.1.5 on my server and when launching it, I got this error. Since it's not a development environment I guess I'm not supposed to ignore the message but don't know what to do about it.
This is the error I received in my console:
"Reference map 'memoryleakfix-fabric-1.17+-fabric-refmap.json' for memoryleakfix-fabric.mixins.json could not be read. If this is a development environment you can ignore this message"

Forgot to close this. Sorry.

i cant tell if that means you fixed it or you gave up lmfao, if you remember how you fixed it would u mind letting me know?
i dont really think this is a huge problem anyway since later in the log it says that memleakfix patched stuff so its not big

did you fix this?

Forgot to close this. Sorry.

If you look at the explanation above you'll see that it's not a bug and isn't something that needs fixing. Unless of course it causes a crash which it hasn't for me and by the fact you mentioned you see later parts of the log it implies your game doesn't crash either.

No, it doesn't crash it launches normally but take about 30 mins to do so. But I don't believe that is the fault of this mod.

Does it crash? If not you can ignore that message.
It appears due to the fact that this mod does a couple workarounds to work on multiple versions and loaders all with the same code.
