user27896: I’m trying some practice games against Stockfish level eight. I always lose but sometimes Stockfish makes obviously bad moves and I get ahead. Here for example, Stockfish makes an inaccuracy followed by what seems to be an obvious blunder. I believe Stockfish level 8 is supposed to be ~2500 level, but I think a computer would avoid basic blunders. What causes such a misevaluation?   

user825: It must have been a bug. Lichess's Stockfish 8 has the following internal settings:

Skill level 20/20
Depth up to 22
Think up to 1000ms

I got the following information from the source code in Fishnet. Not sure how strong it is but definitely not a level that would drop a knight like this.
