Setting control_net_unit_count via sdapi/v1/options to 4 changes the the value in the remote UI but only enables 3 when running a prompt

[fawnha]

I am trying to run a prompt with 4 controlnets via API. When I change the control_net_unit_count value to 4 in the UI on the remote machine, apply the settings and reload the API the prompt uses all 4 controlnets, however if I change the value of control_net_unit_count to 4 using sdapi/v1/options and execute the prompt it only uses the first three conrtolnets. Strangly, if previously the number of controlnets was set to 3 and I then run the sdapi/v1/options call to set it to 4, when I reload the UI on the remote the number of active controlnets has become 4 so it seems like the server at least tried to change the number of active controlnets. Is there anything else I need to do to change the number of active controlnets via the API?

you need to restart or reload the server

while not exactly the case. it's easier to think that the API is basically a hidden UI

some setting requires reloading of the UI to apply because otherwise it isn't updated (so it is just visual)
other settings like control_net_unit_count goes even deeper as it creates the number of corresponding UI inputs
and this only happens during load / reload
which means you can't change control_net_unit_count on the fly, you have to reload in order for create the corresponding inputs to be created

btw I made a PR to add a new api /sdapi/v1/server-reload-ui
so in the future you should be able to just do a reload-ui via api
and don't need a restart or performing a manual reload via tha web frontend
