    Hello, it looks like Aternos has updated the Fabric 1.17.1 loader to 0.12, which has caused some new issues which I haven't experienced in previous loder versions. I have managed to get a private server up and running a day before the update was made.

    I'd like to ask if it's possible to revert to previous loader versions, cause I think 0.12 is still in its early stages (Fabric team themselves say 0.12 isn't available normally) and might have some issues that older versions can fix.

    Download your world and keep a screenshot of the mods you have then reinstall the server. After you reinstall the server upload the world and install the mods again then see if you face the issue. It has worked for some people so you can try it out and if you still face issues with it then you will need to wait for fabric to update. Answering you question "if it's possible to revert to previous loader versions" no it is not possible to do so.
