I'd like to see something in a patch where they fix it so, if you still have all the items or the ones you didn't get to turn in, you can finish the quest.

What are you talking about? Sorry, but I don;t understand what quest or "fix/issue" you are referring to.

Im guessing the thieves guild larceny items for Delvin. It is bugged if done out of order. Even if you do them in order most times it wont accept the last item the eye. I cant get the trophy rewards for the shelf to appear nor the last item for larceny.

The littany of larceny, Delvin won't take the falmer eye, but that is only a very small part of the thiefsguild problems. The guild is riddeled with other small bugs and oddities.

- Delvin taking wrong stuff from you when you return from a fishing job. (he askes for a silver ring to be pickpocketed, but if you happen to have a self enchanted pickpocket-silver ring, he will take that from from you inventory, even if you are wearing it, same with the circlets and amulets he askes for)
- Vex not training anymore.
- The littany of larceny items falling from the shelf or desk.
- The quest for the remaining larceny items getting stuck after 75 jobs (these items are fixated to the shelf they first appear on, so why not the littany ones?).
- The guilds safe poping open a second time.
- The guildmaster chest no longer filling.
- The practice chests not resetting to locked.

I bet I forgot some issues but this is what I remember from my 3 chars trying unsucessfully to complete the thieves.

Oh I see. My apologies OP
