Is there a workaround?

Continuing the discussion from deltaSince or historicState sometimes returns null on openHAB 3.2:

After several hours of research I think i found the root cause. If the trigger overlaps with the timing when an archive in rrd4j is created (e.g. per default every hour, week, year, 5years and 10 years) it could happen that the persistance function returns null. I have tested this on different hardware and different operation system - everywhere the same.

I think I have a similar problem - my water meter rule calculates hourly water usage, so I see some random null values of “current_value.historicState(now.minusHours(1))”, it works most of the time but fails every noun and then.
Can I ask if you have found a workaround to this issue?
