Few bugs I encountered in my playthrough 2.47.8:
Navarro Marisa bugged (talking to her crashes the game, rewriting script from previous version fixed this)
NCR Elise (Ranger girl) - when sent on mission against slavers, ended in another location (not slaver camp, but farm)
The Glow - killing Molech creature crashes the game
Den Residental - I can confirm it is working after replacing dcdealer.int from older version
Slaver Camp/Sulik sister - even after copying missing camp file and replacing her dialogue file rtibec7.msg, (which both fixes relevant crashes) the game crashes when: trying to open her cage; or when talking to her, after her release in the Primitive tribe area -> she cannot be saved
Companions are not levelling (the message says the got level up, but HP are not changing - I am levl 30, Vic still has 70 HP and Cassidy HP 80, jave them all the playthrough). Update: Companions do level up, but after save/load, they are reverted to basic stats.
Combat seem totally broken: armors/DT/DRs are not working/working strange? With 95% DR in Advanced Power armor, basic pistols give me full damage. Almost every burst from anything kills anything/anybody.
Talking to hubologist celebrities crashes the game. Copying fchuavki.int from pre- talking heads version fixed this.
