I haven't been to the theives guild hideout in quit a while and the floor where the pool of water is deeper, and also brighter (the whole rooms alot brighter actually), i know its deeper because i use to jump over the fence and now i cant.

the room im talking about is the one with the fence/other merchants

Who knows? I doubt a change like that would be documented. Heck I'd chock this up to you being mistaken about how deep it was before.

You must be high, they definitely didn't change it in any way. Check the patch notes if you don't believe me.

As far as brighter....depends on time of day....

Dont think they changed any quests yet. I think that kind of bug fix will happen next month

Did you even read what he said? Lol. Or just responded to thread title only?

Did you happen to sell a lot of mead around Riften lately? They're located in the sewers afterall.

That room with all the vendors that you're referring to is the Ragged Flagon in the TG. The other wide open room is the one you can sleep/store your stuff/eat/live in is the Cistern.

I haven't seen any patch (or mod) to date that changes any of this. Especially since these areas involve a major faction quest line. What version are you running?
