Hey there,

Today we’ve updated our convox rack (version 2) from version `20210208170413` to version `20210319134118` and only after the update was successful did we realize one of our apps currently running on the rack went “offline”.

What happened was that, before the update, the abovesaid app was rollbacked to a previous release because the latest release wasn’t working. After the update the app did try to ZDU to new processes, however instead of creating new processes from the currently active release, instead, it created them using the latest release.

We think this is a bug. What do you think? Is this something could you please look into and perhaps fix it so that in the future we don’t get bitten by it if we’re in a similar situation?

Thank you.
