Recently, while trying to debug the case of someone’s defition recomputing multiple times after any canvas update, we have discovered a pesky bug in Human plugin.

It was caused by the behaviour of Dynamic Geometry Pipeline component, which seems to expire multiple times when “Empty” data is provided as Layer name input.

See attached file.
