Aristois

'(I believe you're talking about fabric API, not loader)'

@dyiing What I've been trying to do is taking the Fabric v0.13.3 file from /libraries/net/fabricmc/fabric-loader/0.13.3 and use it to replace the file causing the error in the screenshot. I'm guessing here, but given that installing/running Fabric normally doesn't create the /loader-v2/ folder, that's Aristois's version of the /fabric-loader/ folder, and so replacing the file in there should make Aristois run a different version of Fabric. Problem is the file gets deleted and replaced on launch so it's kind of moot.

Hope that clarifies a little. Either way, thanks for the update, will wait for the launcher update.

Trying to run a modpack on Fabric, however every time I try to launch I'm getting this error.

Tried to switch the Fabric version to the latest in the specified folder, however Aristois overwrites the file on launch so I can't do anything about it that way. Is there any other way to get it to run the newer version of Fabric? There's not any other compatibility issues I can see.
