Manual geometry component selections saved to groups as well as some manual geometry modeling operations from SOPS like the polysplit hugely inconsistent from version 18 to 19 and I've had this issue in previous versions before. That is a very very very unfortunate problem if yo do manual modeling in houdini and go to a new version, open your graph and everything is now botched! UVs that depend on selections are totally screwed and so forth. This is bad bad bad. Bad bad bad!!!!!!!!!! I'm experiencing all types of ridiculous inconsistencies with the group SOPs, polysplit SOP, UV Edit SOP, Edit SOP. Maaaan wtf. This is not good!
