I looked for this on here already, but if I missed it I apologize.
I went to reorganize my party while doing the campaign and noticed that if I was partially scrolled down the page, the box holding the wolf would not match where the cursor is.
If you are scrolled to top of the page, you can rearrange just fine. Whatever box you grab to move will be where you place it, and the box stays right over the cursor.
If you scroll down slightly and grab a box to move, the cursor stays where it is but the box jumps up to be above the cursor. Wherever you move the cursor to is where the wolf will go once you let go of the click.
If you scroll down even further and grab a box, the box is gone visually, but you can still move the cursor and place the box, which will make it reappear. In the last screenshot you can barely see the bottom of the box cutting off Midnight Gloom's name. If I scroll down further and grab a box, it simply won't show up since the distance between the box and the cursor is so large, and you can't move wolves lower on the page than their designated group box.
Here is an attempt at getting screenshots , though my cursor doesn't appear in those, so I have drawn it in. The middle picture is the most obvious since it cuts off the words at the top. I have a video as well I can provide to mods, I am just cautious about my information. I have left in the top and bottom parts of my browser and screen so you can see how far down the screen is each time. I think I covered enough of my info, too. I am moving the wolf named Sand Bar in each photo.
I am using mozilla firefox on a windows 10 desktop computer, with an XP-Pen art tablet for a screen instead of a true monitor. Lorwolf is set to 100% resolution, I am not zoomed in or out.
