Ever bought a Butterball turkey with a pop up thermometer in it? Those things finally pop when the poor done bird has been killed a second time for sure. People fall for them though even though an instant meat thermometer and common sense would have told them that pulling the bird out an hour or more earlier, and letting it rest for 20 minutes might have kept it edible.
I have about the same amount of faith in indicator mud. From what you are describing, the surface may have gone from pink to white but the rest of what you patched is trying to dry underneath your primer---and if you could see it is/was still pink. I think this because it is only happening where you patched.
Whatever you do, do not cry. We will help you if we can.
I bet the primer calms down as all dries but if not, as suggested, host some pictures and point us to them (I am not sure you can attach until you reach a certain number of posts). Do describe what you mean by bubbling. Many of us have seen strange and mysterious things over the years with paint bubbling. I guess we all cried a time or two. Or used the language of the devil. Most causes are easy to source by the time we get out of the business.
In the future, you might think about learning to mix your own dry mud for these kinds of situations. Bags of the stuff cost very little and if you store one opened in a Rubbermaid container it will last a long time. Hot mud is sold by the theoretical number of minutes it takes to cure in 5-120 minutes. It is nice because you can control its consistency. 20-45 is probably a good starting point for a diyer. Mix small amounts in a nice mud pan. You will not need a color indicator to tell you when it is dry. A nice drywall pan will come in handy as will a wide knife.
