Yesterday, I started a new DiD character on Master difficulty for the first time. After visiting Riverwood and clearing out Embershard Mine, I decided to further clear out the unmarked Bandit camp that's south-west of the Guardian Stones for the Treasure Map one of the Bandits is guaranteed to carry. I was level three at the time.
I got there, the Bandits understandably attacked me. The two melee Bandits were barely doing enough damage, even on Master difficulty, but suddenly, I dropped dead. I thought it was some strange glitch that I've never heard of, so I ignored the DiD rule, reloaded and went back. I managed to kill the two melee Bandits and as I was rushing at the archer Bandit, I notice that it was a FREAKING BANDIT MARAUDER. While I was level three! Aren't these guys supposed to spawn way, way later? I deduced that it was he who managed to kill me the first time, so I fleed.
After that, I decided to make Anise's Cabin my own. I swam across the river and was greeted by a Bear west of the Cabin. I have NEVER noticed Bears in that location. At that level range, I only encountered Wolves, maybe some low-level Frostbite Spiders, but never a Bear.
Is my game glitched or is this a feature of the Master difficulty? Are high-levelled enemies supposed to spawn early on Master difficulty? This is the first time I've ever played on Master so early in the game.

?No but seriously unless you are using mods that shouldn't happen.
