Well, this is interesting. I just re-ran three chunks that failed miserably with the last 1.8 beta. I ran them with the release version of 1.8 and they all came out perfect. Same exact settings as I ran with the beta. The only difference is that when I did these with the beta I had multiple chunks running in the batch. This time I just did one chunk at a time with the same batch script. I will have to check later if the problem was caused by having multiple chunks, or if that’s just coincidence and something major got fixed in the release version of 1.8. Either way this was a very surprising result, because the difference between what I got a couple days ago and what I just got now is night and day.
