Hi! This is the friendly automated conda-forge-webservice.
I tried to rerender for you, but it looks like I wasn't able to push to the patch-3
branch of traversaro/gazebo-feedstock. Did you check the "Allow edits from maintainers" box?

NOTE: PRs from organization accounts cannot be rerendered because of GitHub

There is not any particular change that required the rerender, so this is not blocking the PR from being merged, but this is definitely strange.

Also on the ignition libraries if you want.
