So a post update update....
A bunch of quest bugs have been fixed on production already so all the quests work fine.
A crafting code bug which was creating stacks of 0 items has been fixed on production.
A crafting code bug which was creating crashes due to stacks of 0 items has been fixed on prodcution.
Whats left.
It was not mentioned in the rules update change log, but it is now possible to do much much more bulk crafting, this time with combinations. So when you would combine 1a+1b=1c you can now do 65a+65b=65c in one go and no longer need to do it 65 times. Where this is possible it will show as the following 'combine 1a and 1b into 0c' that 0 in the crafting book acts as a wild card so the number it makes depends on the number of items you give it. The items need all be exact multiples as well, so, 10a+11b=/=10c + 1b left over.
However there is a bug in the crafting rules which was not fixed prior to release. This is if you have the same starting item making two final items which are multiples of each other you only ever get the first item the server finds, for example.
2a = 1b
and
20a = 1c
If you give it 20a to try and make 1c you will always get 10b (10*2a).
This will just require someone to edit the crafting rules to fix it.
Thanks to all who have reported bugs so far.
