Deployment failed: which version is deployed where

I promoted yesterday a staging version to production, this deployment timed out.
Now I am really confused about the situation in the deployment logs:

  • There are no more Staging and production tags in it
  • On the editor, both staging have a last updated matching with this failed deployment thus, I wanted to promote the staging onto production not the last state of the editor to staging or anything like this

Does anyone has an idea how to know which build is deployed on which stage in my case ?
Could I maybe find it out using developper tool ? I do not know if my front version matches my back version anymore and this is quite uncomfortable
