I was using the D&D 5e character sheet from Roll20. I think this is an issue with the core engine though, not the character sheet, but I haven't tested with other sheets. Bug Description and Reproduction:  When I had two D&D 5e character sheets from Roll20 open, one on top of another, I tried dragging an item of equipment from the compendium to the character sheet on top. The item instead went to the character on the bottom. I also couldn't delete items of equipment from the top character sheet. Work-Around:  This can be worked around by closing the bottom character sheet, but this can be inconvenient. Why it Matters:  Having two sheets open at once allows a comparison of the sheets and the fixing of discrepancies between them. In this case, I was making sure one character had key equipment that the other had. Having to close one sheet every time I make a change is inconvenient.
