Of course, my toolset was quite buggy to begin with. I was already getting toolset errors whenever I started my toolset. I had a ton of prefab placeables which were almost assuredly causing the toolset errors. Removing the prefab placables didn't help, so I'm currently stuck uninstalling and reinstalling NWN2.
Also, someone gave me a 9.25 on the Vault. I don't think I'd rate myself that high. There is much that I could do better and the scripting/quests are quite pretty straightforward. So I think that person is being kind to me.
