Open-Meteo always returns the requested number of days but fills the ones past the model's horizon with nulls: the last one or two with the default model, nine of sixteen with icon_seamless. format_multiday_forecast called int() on them, so the whole reply became the multi-day error (gwx 15d for London and Reykjavik on 2026-10-01; gwx 7d under icon_seamless). It now stops at the first day without a high and low. The tomorrow forecast and the default reply compared a null precipitation probability with 30, which raised too; a null probability now just leaves the precipitation out, and a tomorrow with null temperatures reports that it is not available.
