Keep close tabs on the underside of your oil fill cap. If it gets milky or sludgy then you've got a coolant leak into oil. Also get under jeep after sitting all night and check the FIRST drop out of a loosened oil drain plug. If its water you have coolant in your oil.
If neither of those, I'd change both your fluids and just keep monitoring for a week or so, but if ok you likely didn't do damage.
Don't drive her till you checked both of those. She won't get worse sitting there.
Obviously find what caused overheating and fix that....

I don't entirely agree with this statement, milky or sludgy oil caps do not indicate coolant into the reservoir.
During short trips, the outside of your engine gets very warm, and then cools off, bringing in moisture into the crankcase. You actually have to drive the vehicle for quite some time before you will burn off the excess water. But, the water that doesn't get burned off, creates that milky type residue that you see on the bottom of your caps.
You may also want to refrain from filling your crankcase with Butterscotch pudding. The color of the sludge doesn't specify what it is, a darker sludge may have some used oil in it, not indicating a head gasket leak. The only sure way is to the specified head gasket tests, not just on what could be. You want to know for sure, and guessing won't always secure the right thought.
