Nothing really major but I noticed two things. Sometimes when loading the page part of the page I am viewing will be covered with a green/red background. Sometimes it'll appear with a black back ground and yellow lining. It doesn't cause any freezing but it does make reading rather difficult at times. one other issue is that my folders are incorrect in their numbering. Volume 12 is appearing in folder 5 and I can't figure out why that is occuring. Each volume is in its own folder with the chapters in it and those volumes are within another folder (so I an avoid clutter).
