Bug description

When trying to run the migrations I get:

13:43:24.482 [info]  == Running 20200825061316 Pleroma.Repo.Migrations.MoveActivityExpirationsToOban.change/0 forward

I can't rollback to the previous version I was using because I get:

Please help! I'm stuck on a version that doesn't work and I can't go back
