For one of our Octopus projects, we have Package Re-deployment (in the settings), set to “Skip any package step that was already installed.”
However, for a recent deployment we did to a QA environment, Octopus actually re-deployed existing versions of packages, which were already on Tentacles.
Why did this happen? Please let me know of any logs you may need.
We were running version 2018.5.6 when this occurred, and we have since upgraded to version 2018.8.11 to keep up-to-date.
