I don't understand why I'm level 267 at the trophy level even if I was level 14 earlier, I didn't deliberately glitch or buck to get this level
Probably you just haven't looked at it for a long time and haven't noticed how high your level is now.
What the? My buddy has more trophies overall, but is just Lvl. 30 xD
Maybe it's the "height" of your trophies.
Because Sony changed the trophy system yesterday.
