I started playing again recently but don't have the time to devote to playing the game right, so I used an XP cheat and leveled up to 30.

I am noticing the enemies are more powerful judging by my difficulty in defeating them. And those Albino Radscorpions are everywhere.

My character has 100 Sneak, and has the Almost Perfect perk so all stats are 9.

I just gained entry to Vault 87 and every supermutant can see me sneaking as soon as they are in visual range. They come at me immediately.

Any ideas why that is?
