I have been working on a player home mod for the past few weeks. I created a few sections of the house and I planned on creating quests to go along with each section. I had just finished creating a dungeon for one of the quests. I set up a map marker for that dungeon. When I went to open Skyrim to test the marker my entire computer crashed and restarted. When I opened Steam up Skyrim had been uninstalled. I began to reinstall it and I also opened the creation kit up. I decided to work on the mod while I waited. Upon opening up my mod I noticed that the only quest I had created so far was gone. Upon further inspection I also noticed that the dungeon(Cell) I had just finished after a week of working on it was gone as well. The player home was still there however; when I loaded up the cell it just showed blank space all that was left were a few bookshelf containers and a few book markers. All of the objects I made including Items, Static, and containers were all there and were working properly. It was just the cells and the quest I made that are missing. I checked the file details and it lists the objects I made and the book markers and containers. It also lists aliases from a quest that I deleted a long time age. This has never happened before and the creation kit has worked as good as it always had. If anyone knows how to go about solving this issue please let me know because otherwise I will probably have to abandon the project which at this point is over a month old. If there is any other information that you need or if you need images I will gladly provide those. Thanks in advance
