This is NOT a gamebreaking issue. Murdering the entire upper level (as I did) still allows you to finish the game.
Issue? YES
Game-breaking issue? NO
Get your facts straight, especially when having the audacity to complain to OE about the many 'gamebreaking issues'... *shrug*
EDIT:
Also *gosh* why would this take longer than a text-change? I can fix 10.000 text-issues in TSLRCM in the time it takes for a single other bug... it's not different here. And everyone can understand why (bar you apparently).
You can define "Game-Breaking" differently, but you don't have to be such a jerk about it.
For me, turning one of the major cities and factions hostile is game-breaking. Maybe you just want to be able to kill a final boss and trigger an ending, but I was trying to enjoy the game.
