There was yet another “Bug Fixes” update for the Epic Games Launcher today, but the Fab Library is still unable to update products and plugins. Clicking the update button seems to be working only to have it reappear when the launcher is restarted. It’s been two full months since Fab support was notified of this infinite loop of false updates, but they have said there is no ETA for a fix. Multiple forum posts/comments seem to indicate the problem affects those of us with large libraries. Perhaps we big spenders are a small subset of Unreal Engine users, and this issue has fallen between the cracks?
Please, if this is happening to you, too, let Fab Support know. Maybe we need to make a little more noise.
