Went to level the party last night and one of my players' charactermancer sheets has got stuck on the first page and now will not close or go forward. The HP rolling button has also popped up three times (I'm guessing from trying to open the charactermancer multiple times, see picture). Any fixes or anybody else encountered this issue before? We tried refreshing both our pages, and I cleared the cache on mine, all to no avail. Can exit out of it but cannot cancel. Any help would be greatly appreciated!
