While I know the multiple crafting stations were made to divide recipes and recipes were shuffled around, I also know by modding and hosting a local server that it is presenting some problems.
If you look at the log of a server, in some instances it shows a message when the userdata is being loaded saying “XXXX recipe cannot be learned this way”…
Only because I know that that I went on to fix the problem by resetting the feats and adding them again, because the change was somehow problematic for characters that were created before the change, and have been bearing these feats from a long time.
As I have currently 4 steam siptah accounts to play around my machines here with my friends and to test mods, I know that it causes some players to simply not have the recipe even if they have the feat, “for some reason” (the reason I know, it is because the data was not translated to take into consideration characters that needed their base data changed, and instead the updates were a simple change and replace).
That is also why the update caused a lot of problems with persistence data.
So while I understand why someone would blame the lack of attention of a player, that might not be the case for some.
