Up to reaching level 20 and 142 hours gaming:

1. Numerous periodic game 'crashes' (game stops running).
2. Quest--Heartache by the Hunter--finished but did not gray out and relocate in list. All quest/option items on right solid and grayed but left side still open.

That's not to bad really...

Two irritations... I forgot about this from FO3 until visiting Vault 22 yesterday in FONV... Your local in-game mapping feature svcks. It may be the worst local mapping detail I've ever seen. And, I trust you will be doing something different graphic engine wise for FO4? Character has gotten herself stuck between rocks and hard places 4 times exploring around but has learned to save _very often_. Objects and creatures can often fall through the ground/floor and are lost. Perspective is way off in some cases. Character feels like it is three feet high when it really should be closer to 5+ feet. Some terrain roads are way to steep of a grade. Cannot climb over/scale some interior hills. Etc.

1. Only solution so far to either the game stopping or the launcher stopping when trying to launch or the game stopping during play is to save often and simply restart the game--even if problem repeats immediately. After a couple tries sometime the game will start to run and run stable for prolonged hours without any problems of this sort.

2. Heartache by the Hunter cleared itself properly after other quest(s) were resolved which ultimately included talking to Jackson at the NCR Outpost however I was in the dark on this until I read the 'spoiler' here to pursue the BoS quest(s).

The game's mapping feature continues to be an irritation for some complicated caves and for all vaults--what a helpless mess.

Different graphic scale errors and perspectives periodically produce a chuckle from me marveling at the difficult programming choices that must have had to be made.
