Hi all,
I'm experimenting on a building generator, it has been in a subnet that later converted to HDA
But I find that there are two merge nodes now….
One square and one round…
And the round one, merge (utility always have )

I don't think I have done something crazy in Houdini's folder,I'm just working on the object network.
Every time when I open Houdini, it pops out this error window..
Why it is so easy to wreck the nodes from the application's user interface….
Is there a way to restore default node definition? I find even re-install it will not help unless you delete every remaining folder linking to Houdini…

Houdini version: 16.5.473
