Rollback error misfire

  1. Rollback (I'm using the Rollback rights) successfully performed but got this notification "Sorry, there was an error performing a rollback." popup at the bottom for 95% of the rollbacks I performed using UV and also the purple loading bar will be stuck at "Preparing". Having the notification popup also prevent UV from auto-reloading the page to show the latest diff after it has performed the rollback.
  2. Post-rollback actions button doesn't display when using Rollback rights, not affected when using pseudo-rollback.

Attempted to reproduce, could not.
