Just wanted to report the following exception that Rule Machine just threw me:
2019-12-04 08:30:52.200 errororg.h2.jdbc.JdbcSQLException: Column "disabled" not found [42122-197] on line 587 (ruleList)
I'm running the latest update to the Hubitat platform, the one released a couple days ago.
I would provide more context, but I wasn't actually doing anything with Rule Machine at the time. I just happened to see this when I was looking at the logs for something else, so I unfortunately don't have any idea of the context/cause.
