godot/scene/3d/soft_body_3d.cpp
PouleyKetchoupp 195eda244f Fix spamming errors when SoftBody pinned nodes have no attachment 
There was a specific case where the node path wasn't checked for
validity before trying to access the attachment node.

It could cause lots of error log noise in both editor and game.
