For some reason no one related to the thieves guild has any topic in their list of topics other than rumors. For example when I go to jail and that lady comes to talk to me about the thieves guild she shows up but only says "greetings" or something like that and only the rumors topic is listed. So I console commanded myself into starting the "may the best thief win" quest. The other two thieves run off and I beat them to the diary and my journal is updated. But when I go back to the guy to finish the quest the only topic is rumors. I am using FCOM and other mods, I think some of them might influence the thieves guild. I know I have the "you need to sell more stolen items before you can progress further in the thieves guild quest" mod but should that do this? Does anyone know what the solution to my problem is?

The people greet me with the usual "Greetings blah blah blah" stuff. Then when the topic pop up the only one available is rumors and nothing else. Usually the quest dialogue would be like "Oh so you were able to steal the dairy.... You are now a full member of the thieves guild... your next task is to....." and then there would be a topic like "Next quest" or something I would click on to start the next quest. It's just not there and the only greeting I get from anyone on the thieves guild is the regular you talk to a random person not related to any quest greetings, and there are no topics to start the other quests.

I'm not sure if this is just related to the thieves guild. I know random people not related to quests have other topic like "Gray Fox" and "Heronimus Lex" and I can still go and shop at shops. Even the beggars don't have the "have a coin" option, and they talk to me like a regular person, not with the beggar greeting.

I also do not know if other guilds have this problem. I joined the mages guild far enough to make spells and enchantments, then I stopped. I haven't gone back for a while and so I do not know if the mages guild will have this problem (or other guilds for that matter) I'll look into that and see if this problem is more widespread then I originally thought.

Has anyone else had this problem and does anyone know what to do? I have played this game many times and this problem has never occurred so I think it is a problem with on of my mods. The only major mod that I have installed that I have never used before is FCOM. Has anyone had any quest problems with the thieves guild and FCOM before? Thanks.

Sounds like a problem many people had with an early version of Ren's Guard Overhaul. Are you using it? Is it updated past version 2.04?

I don't think I'm using Ren's Guard Overhaul. It's not a esp that I have selected, could it be part of FCOM or another mod?

did you move from the SI to the vanilla worldspace in any way other than the normal way?

I might have done the fast travel to Frostcraig Spire spell given in Frostcraig reborn, in fact I think I did. Is that the problem? And if so, is there a way to fix it?

Yep. Just go back to the strange door on the little island, and go thru it, Pass back into the tamriel worldspace if that is where you currently have business.

If that was the issue, though, wouldn't he be getting the "I HAVE NO GREETING" text? And wouldn't it be affecting all NPCs, not just thieves guild members? (Genuine questions, not trying to be sarcastic.)

Also, if it actually is the Shivering Isles issue, an easier way to fix it is to enter "setPlayerInSEWorld 0" at the console rather than traveling there and back.

I was finally able to play Oblivion and tried the SI fix and now it works. Thank you for the help, I was not expecting the solution to be so easy.
