After I purchased all all-on of the brzzedhome from the steward(including the children's room and a table which can make poisons), it crashed when I tried to enter it. Then I tried to enter it without purchase any add-on. It still crashed. I didn't install any mod that has any connection to breezehome but the three Unoffical Patch (Skyrim, Dawnguard, Heartfire). Do they have conflict to the breezehome? I have found something on other forum that players faced the same problem without install the Unofficial Patch.
