When you have enough buffs to be close to the buff cap, they overlap your debuffs so that the debuffs are not visible. This makes it very hard to track the timers on debuffs you have, and even to know which debuffs you currently have. Problem persists on both Simple Square preset and Faded Square (user submitted) preset. Best fix would be to allow to move (by dragging?) the debuffs lower in the screen, so the buffs wouldn't overlap them.

Debuffs have nothing to do with SexyMap.
