Simulating River system, forcing spine to not empty resivoir

[Andreas-Soderlund]

Hi! We are a group that is simulating a river system with Spine. We have gotten it almost done, but we found out that Spine is breaking our boundary with fix_node_state that we set for the end of the simulation and uses the whole reservoir. I have tried to look for a way to put a price for missing this, but can't find any. Right now I have fix_node_state as a time series that fixes the level at the beginning of the simulation, then goes to NaN and for the last hour is set to what the level should be in the end.
I thought to try to set an initial_node_state and a time series for node_state_min (0 for all of the simulations and required level at the end) but when I try to run the simulation I get an error "LoadError: Unable to set lower bound to NaN. To remove the bound, use delete_lower_bound."

Any help on why I would get this message or another angel of attack to solve this isue would be greatly appriciated.
