in my first run, i discovered somewhere a full X-01-set with lvl 31^^
now in my 2nd run i checked this place out with lvl 6 and i found a T-45 set.
i quit the game and reloaded my save from sanctuary before i startet the search and never came close to this location again.
my next try was with lvl 20 and i still found a T-45 set... no T-51 or T-60^^
...so i loaded a previous save from sanctuary and avoided the place again!
now with lvl 31 i still get only a T-45 set while i've gotten a X-01 in my first run (lvl31 too)
this is why i think that FO4 has some hidden or secret savefile where it saved my first attempt to get this power armor!
anyone else noticed such an odd behaviour somewhere?
