Been playing Crysis again (or indeed, for the first time, seeing how far I got last time) and I've already encountered 2 major bugs

1) Recovery - after I killed the tanks the next objective didn't show. I could, however, continue by following a walkthrough for where I was meant to go and thankfully the next level did trigger.

2) Relic - The "get to the excavation site" objective never triggered completion, even though I went inside and did the cutscene. Again, I followed the walkthrough for where I was meant to go, more enemies had spawned for the way back, but the final enemies (nanosuits) didn't, meaning I couldn't continue. Guess I have to go back and try again

From what I read, these bugs are caused by not taking the expected path to the objectives, which seems like a really poor bug.

Either that or you're a poor player; forget checking out those good looking trees, stick to the objective path nub

I know I took less than usual paths for a lot of the traveling and never encountered these. Odd.

Well the first one is apparently caused by going in the front entrance of the bace, rather than round the side. The second I guess is caused by not going in the main entrance (I snook up the back).

I did manage to trigger the "clear the landing zone" objective last night (while the excavation site one was still incomplete and one objective was missing altogether), but still no Koreans.

Buggy is an understatement.

I wasted many hours of my life on one of the particularly long missions - the only solution was to start the zone again from the very beginning.
