I agree that the biggest change could be moving to bridgessi. Perhaps it has other stuff besides mescaline that precipitates as an oil citrate.

Do you have more bridgesii powder? Can you try to precipitate with fumaric acid on a test run? Orchidist got xtals with fumaric ad oil with citric  Maybe extra alkaloids need fumaric to not oil up. This all speculation, but maybe worth trying.

You can also add Fumaric to your jar with oil and shake it up. It may react with the oil and xtalize, IDK.
