Unable to select multiple body parts in scene that are selected in scene tab
I know it may sound like a confusing title. I used to be able to select mulitple body parts of G9 in the scene tab, then go into the parameters tab, and select all those parts at once so I could change the limits or lock those parts nodes rather than doing it one by one. Now, after I select the parts I want in the scene tab, whenI go into the parameters tab, I can no longer select them all at once. I didn't change anythhing that I know of.

Are they listed separately? If you open the Parameters pane option menu (the lined/"hamburger" button in the top cornere, or right-click the tab) and look in Prefernces what is checked? You want Consolidate Properties (so that you see only one slider for any given property across selected nodes) and display Separate Items unchecked (so it doesn't separate the nodes entirely)
I checked under Preferences in the Paraneters pane, and Display Seperate Items wasn't checked, so I did, and now I can do what I could earlier, so thank you, Richard Haseltine.
