Question about ControlNet Chain

[Rabbitovski]

In StableGen workflow, if I apply more than one ControlNet units (Depth, Canny, Normal),

It will create multiple LoadControlNet and ApplyControlNet nodes as expected, but only one SetUnionControlNetType node (#239) will be created, which will be the input for all ApplyControlNet nodes, instead of creating multiple SetUnionControlNetType nodes for each corresponding ApplyControlNet. Therefore, some LoadControlNet nodes seem not to be applied in the generation process.

In the image below, or in the workflow.py line 648, we can clearly see.

Is this by design or is this a bug?

More likely a bug. I will look into that when I have some time.
