I am in the final stretch of the game, unfortunately, I cannot do 100% completion due to the broken gigs. I now have six in total which doesn't want to trigger completion. Out of nowhere, 2 gigs I did around 20hrs into the game randomly triggered completion about 60hrs in... don't know, don't ask, I wasn't remotely close to where these gigs took place when it triggered and these are all gigs which becomes available after the interlude. I reported these issues to CDPR after I believe I have played enough to file a comprehensive bug report.
After I am done with the game I will post my final game time here. Just for notice, my Steam playtime is wrong, the game keeps on running in Steam even though I exit, but the game save tracks the game time.
Another guy who claims 100% completion (incl. every Steam achievements) have his game pegged at 93hrs. I know people are downloading trainers for this game, so I take some results with salt.
