Error in reserve_t

[e-zaline]

I have set a constant reserve up of 10 MW. In my reserve_t output sheet, when I sum the reserves that are procured, I obtain almost always 10 MW, except for a few timesteps (see below)

It could be related to reserves in VRE (i.e. plants with a profile) wich are the ones in my case that have very high values when contributing to the reserves.
