Yes there are, but you have to be extremely careful, and many things you do can break other quests and you're unable to finish them if you do. Hopefully, the upcoming patch will fix some of them. If not, modders will as soon as the CK is released.
For instance?
I have never experienced any quest bugs from exploring, 200 hours played.
Well, a lot of that has to do with luck tbh, and most of the things that are more
easily broken than others are smaller quests.
Especially if you don't want to spoil your game by checking the wiki or w/e, you gotta roll with it, and not cry too hard unless you run in to game breaking (or mq breaking) bugs
