Any limit to # of Remains in Play?

[StayPuft]

Okay, so I am starting to run out of questions for which I completely do not know the answer. LOL! But, being a perfectionist, I still like to clarify on things even if I am mostly sure, but just not 100% sure.

So, this is another one where I am pretty sure I know the answer, but wanted to clarify anyway.

Is there any limit to the number of "Remains in Play" cards the zombie player(s) can actually have remaining in play at once?

As far as I know there is not. However, I ask this because there have been several games where the zombie player(s) wind up having so many "Remains in Play" cards in play at once that it was almost mind boggling. Just yesterday in my gaming group, I was one of two zombie players, and at one point we must have had at least 5 or 6 out there at once. Sadly, none that were all that helpful to us. LOL! I specifically remember a couple lights out ones, a taken over, and the heavy rain one (I forget the exact title, but any hero starting their turn outside subtracts 1 from their movement roll to a minimum of 1).

So, again, any limit, or can you just pile them all up, even to the point where you could potentially have every single one out there in play (though that may be very unlikely to happen, LOL)?
