Weird Internship experience

Ive been working at a PE/I-banking internship at a midsized firm in NYC area. Although most of my internship class are seniors from top targets, I'm just a rising sophomore at a semi-target. I had been doing a good job and spoke on a call where the managing partner was listening and he personally called me asking me to stay on for the rest of the summer, (I was suppose to finish a few weeks early to go to California.) Which, was kind of strange imo.. Then things started getting weirder- I was transferred to work directly for one of the partners and I am now assigned crazy big roles (stuff no other interns are getting and most analysts wouldn't either). I frequently am told to run point on calls with other banks-??? literally when there are analysts on the line. On these calls, I don't say what my role at the firm is other than "I work under ____" but a few people who I have called have proceeded to add me on Linkedin where they can clearly see Im a intern- and a young one at that. My manager has now asked me to play golf x2, both of the times it was with a CLIENT?! thank god I can shoot a 45. Even HR has started not caring about how many hours I log.. I think I did a good job at the beginning of my internship, and Im probably one of the best interns in terms of accuracy, understanding, and speed. But this is just weird at this point- does anyone have a similar experience?
