Crusader Kings II

[Hooahguy]

Something which has been troubling in my recent 4 hours of playing today is that there doesnt seem to be a way to clearly see which lands are yours. Currently Im playing as a duke in England, formerly King of Scotland and Ireland. Pretty spectacular downfall, Id say, I mentioned it here before. Anyhow, after a slew of wars my current king died at 40-something from a heart attack leaving no heir, as all of them died as children except for one who died of the plague or something after he married and had kids, which sucked. Anyhow, his grandson or something became ruler so that kind of messed up my precious few lands that I held to a point where I really have no clue which lands i own. I thought I could go to my titles bar and check there so I thought I knew everything, but then when civil war arises I find that I held another province somewhere else that I had no knowledge of. Anyone know how I can find out what exactly I own/my vassals own?
