The weather plugin makes use of incorrect terminology, falling for the common mistake of substituting "astrological" when meaning "astronomical". This is possibly due to a translation mistake. Astro_log_ical is anything but "logical" and is an ancient fiction to do with predicting the future from the stars. The correct term for moon phases and such like is astro_nom_ical
That's right, but this mistake has been fixed ages ago. Are you sure you're using 0.8.2? I'm closing this as I can't find any "astrological" strings in the translations or the code.
