I've created a large roadmap planner and it acted normally. I went to edit today, and every time I hit the edit botton, most of the lanes disappear except for 4 and most of the text dissappears, though it does retain a couple words (almost like it's reverting to an earlier version). When I cancel out the entire roadmap comes back.
Any help in trouble shooting would be great as it took me quite some time to make this (the editing window is a serious pain and you have to drag new bars down the lanes instead of creating them in the ones you're on - this was agonizing, and clearly a big mistake now)
