## Issue being fixed or feature implemented Fix failures like https://gitlab.com/dashpay/dash/-/jobs/6120923632 ## What was done? Handle disconnects and reconnection of the revoked MN in the right place. ## How Has This Been Tested? Run multiple `feature_dip3_v19.py` in parallel a few times ## Breaking Changes n/a ## Checklist: - [x] I have performed a self-review of my own code - [x] I have commented my code, particularly in hard-to-understand areas - [ ] I have added or updated relevant unit/integration/functional/e2e tests - [ ] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_
