Yes sometimes there are changes to the node databases that aren’t forward and backward compatible with the earnings script. I try to make sure there is always an update available within a week of release of a new incompatible version. But keep in mind, my nodes are on docker, so I’ll be one of the last to get the update. If you run unto any issues, always make sure you are running the latest version of both the node software and this script.
For the fastest response, post any issues on the original topic, then I get a notification about the issue as well.
