FYI: Don't take a box when you don't have space and very low time
The window to adjust/switch units opened, I had 1 stacks, while I was making space the timer was up, the day has pass and I lost every unit on that box. RIP. Reported the bug ingame, but probably good to up this for visibility and to warn others. I lost it in Sprint and barely lost that second fight, the Box might have been the difference
