Hrm, haven’t tried crafting one yet, and I know it won’t help you as such, but I did obtain a few two days ago just by killing a Cimmerian in the mounds.
I wanted to play the updated game, but since I like cooking, and I have a lot of feasts (1 improved fridge to every type) I don’t dare to play… Had (and I guess still have) similar problems with a mod called “epic feasts”.
From what I can see, the problem would manifest on the server, not on the client. If you’re playing on a server, it won’t matter if you logged in or not. If you’re playing single-player, then you might have to wait until they patch it, but that might take a long time if they don’t prioritize the fix.
Lasting Feast is also missing as an option in the thrall ui for their dietary options, showing onyl 9 options + 1 empty spot on position 8, where Lasting Feast used to be.
Does not matter for me anymore. I opened up steam to play. Usually I play in offline mode, but (for updating mods I guess) last time it was online. Luckily I noticed that, and before starting the download, I switched to offline, but it was too late, the game crashed on the main menu. I updated, and all of my feasts are intact.
