Well, as all of you already know... Skyrim is the game of the year and also the game with most glitches of the century. I will be posting what are those glitches and what they do and how they affect the game experience. So far these are the glitches I've encountered.
In the Winterhold College radiant quest: The mission you get from Sergius to bring him a random quantity of a random soul gem, if you have in stock or in your house some of those and you try to get them and bring them to him, it won't work. The game won't recognize that you have the soul gems. Apparently you have to find them from that moment on. Also, in the Arniel's Endeavors radiant quest part 3, Arniel will give you a warped soul gem and a fire spell. You have to find 3 dwemer convectors and put the soul gem in it and use the fire spell to heat it for 3 seconds. Probably, you already cleared some dwemer dungeons where you can find these convectors. BIG RED WARNING!!!! Don't use those convectors. If you do, the mission will glitch and won't update after you heated the soul gem in the third convector and it will still ask you to heat it a final time. When you do it again, the game won't recognize that you did it. Use outside convectors or convectors inside uncleared dungeons.
Another glitch and an annoying one is if you wait to do some radiant or additional quests from a faction, you probably will risk to not get it at all. Example, I waited to do the thieves guild radiant quests and additional quests at the end of the thieves guild main quest. When I went to Tonilia to get the Moon Sugar Rush radiant quest, she didn't give the option to do it. That happens in the mages guild too.
Also, in the last mission from the the thieves guild where you have to kill Mercer Frey and take back the skeleton key and the eyes of the falmer. When you take the eyes, you don't get the update from the Larceny Targets radiant quest to take it to Delvin Mallory. In my case, I had both eyes and he didn't recongnize neither of them to buy it from me, but Tonilia did. So, I could sell them to her, so I didn't lose the coin.
That's all for now, so as soon I have more glitches to post I will let you all know.
