Closing in favor of #93.

Thanks for raising this. I agree this is likely caused by the same underlying issue as #93, namely that we have a lot of condition = null rows in the database while the worker re-parses the necessary files after deploying v0.9.6. Our fallback mechanism (the Darmstadt station you posted above never records all fields) gets thrown off by this because it cannot find a nearby station with a nonzero condition.

In your case I suspect this should be fine again once the DWD publishes updated current files in about ten to fifteen minutes.
