HN24, PSUM24, etc
Accumulated parameters such as the 24 hours new snow height, 72 hours new snow height, 24 hours precipitation, etc are corrupted when using a CALCULATION_STEP_LENGTH different than 15 minutes. The code that generates these parameters (both for the .haz and for these parameters in the .met) assumes that 15 minutes timesteps are used.
Unfortunately, the required changes are a little too widespread to fix this bug before the next release. It is therefore delayed until after the upcoming release.
