i don't know but i will say that i am very much a latecomer to using update PCB it does seem pretty cool, but i got a few spooky things just like this and went back to the old netlist load
the board wasn't huge is there a way to destroy the handles it creates ? (or maybe that doesn't matter) the thought i am trying to promote here is what about going back to the old netlist load?
