Happened 5 times to me already today. I've been in /room bootcamp1 (EN1). There are always about 20 mice there. All of sudden there are only 5 to 7 mice left, including me. When I look in the menu, I can see that in bootcamp1 there are 18 (or something like that) mice. While I'm still in bootcamp1 tho. So I go to the 'new' bootcamp1 and it's fixed, but it happens too often.
