In spite of the name, it's not crafts'woman' ;-). I only like that name because my kinsmen and -woman in LOTRO call me that, since all my characters there are female and have the last name 'Blake' ;-)
Oh, sorry, man!

That I need to 'disable' certain crafting recipes because as far as I know there is no way to disable one. I can only take away the ingredients those recipes use.
You would have to exchange the file in the pak file. Should work, shouldn't it?
And if I do not forget I shall add very importand stuff that Larian forgot like for Cyseal's fish seller:
One player missed scissors. How to cut the hair otherwise?
Why did you change trader generation frequencies ? Cannot be because of limited handles. (Because I am the only one paranoid about them ;-)
Changing that will mostly hit crafters because they depend on trader's ingredients, traders are the only reliable source for a lot of ingredients. (Think about the special arrows, where else would you get antlers or teeth ? Most people don't care about that, but crafters do.)
You're not alone (if that's calming for a Paranoid). Since the first time I heard of this precarious matter I developed some pretty fears myself. When will that ticking bomb blow up? And how to handle ticking bombs without, oh God, using handles!
I'm not sure about the relevance of trader restocking. Depends on playstyle (how often you request trades), so the influence of EE is more indirect. It encourages massive trading and crafting much more than Classic did (only level, not time difference relevant). And it forces restocking (more than Classic) when you just come back to buy an item you didn't buy last time (and Classic only refreshed empty slots, if I remember correctly). Well, I see the point: I would hurt those I try to protect.
But there's also a non-handle-related problem I have with the trading system: in Classic I often visited other vendors to compare items. Now I always risk to lose the item (due to time related refreshment) if I don't buy it immediately. And trader assortments (speaking of armor and weapons) become too exchangable with such a high frequency. And third problem: trader items are just too powerful. So the solution would be to make changes on frequency (best only for armor and weapons, not for ingredients) or to change treasure tables (of vendors and/or enemies) in the last case.
So put together: the problem was non existant in classic and occured in EE with more than one person reporting it (myself and others NOT reporting it).
The only thing I can think of that could have a big influence on this is the changed treasure generation, because, what else ?
So ... treasure must be pre-generated. Otherwise it would change after loading.
Yes, that's the big change in EE, to prevent save scumming. To a very high price...
Treasure MUST actually be created on every levelup, because no one would like to open chests, barrels or crates with loot of the level it had when you first entered an area. You can easily get to Hiberheim at very low level if you visit Wally ... or Willy ?. But you would not want level 5 loot in all Hiberheim. You also enter Luculla Forest a long time before you actually really do something there, because you need to enter it to go to Hiberheim. If you open a container in Hiberheim or Luculla though, it's around your level and not much higher I think. And finally, you stay in Cyseal for a while without ever leaving it, you could open ANY container any time, loot should be at an appropriate level and not level 3, the last time you left Cyseal and came back after the second star stone.
I almost said: Yes, Sokrates, it cannot be otherwise! Now I see clearly: items must be pre-generated on every levelup. Otherwise you wouldn't be able to find legendaries since they require a certain level to drop, as far as I know. And you definitely get legendaries (at least in most cases) after a while on the Cyseal map.
So the difference of quality between trader items and looted items only comes from different treasure tables?
If I am right and with treasure pre-generation also comes handle acqusition, it means that the change from 'on demand' to 'pre-generated' treasure in a system without any 'handle handling' might have been the single most stupid change from classic to EE ;-)
I never understood the motivation behind it either. If someone wants to save scum, why not, does not hurt others. After you load the game for the tenth time, it gets old and you go with what you have.
I tend to agree.
EDIT: Do we know what CharacterMoveWeaponsToContainer and ContainerMoveAllItemsToCharacter does in that regard? Does it create handles for all weapons/items?
And do ItemTemplateIsInPartyInventory, ItemTemplateAddToCharacter and ItemTemplateRemoveFromCharacter deal with handles? (I'm scared...)
