Yellow propane bubbles???

So I was packing up this weekend and when I disconnected my BBQ and camp stove I noticed a yellow bubbly ooze coming out of my BBQ propane regulator as well as out of the stove regulator. It was enough to cover a paper towel and well smelled of propane stank. Any idea's of what it could be. I have always filled up at the same place for the last couple of years???

This is just my guess but what you are seeing is the Mercaptin Oil which is yellow in color that provides the odor in the propane

I also noticed this yellow substance when I unhooked my high pressure hoses from the tee on the RV propane bottle. My Coleman Roadtrip grill quit working attached to the high pressure hose from the RV, but still works with the throwaway bottles.

Thinking that the yellow substance might have clogged up the valves on the end of the hose???
