(yes i have the fabric api and malilib)

You seem to have downloaded the Fabric API mod for snapshot 19w42a?
Also my mods don't need the Fabric API at all, so you can remove it unless you have other mods that need it.

i have immersive portals and worldedit

and light overlay

Then get the 1.15.2 version of Fabric API.

So either this: https://www.curseforge.com/minecraft/mc-mods/fabric-api/files/2898702
or this: https://www.curseforge.com/minecraft/mc-mods/fabric-api/files/2879020
depending on which version your other mods need/work with.

so i downloaded the 1.15.2 version of fabric api from curseforge and it gave me the 1.14.4

so it turns out that i not only downloaded the fabric api for 1.14.4, i was also using fabric 1.14.4 to try and run 1.15 mods. I think my problem is solved, maybe.

it is
