Yeah, I asked the same question in my random questions thread. The way it's written doesn't literally say that it needs to be discarded, but the first sentence or something seemed to indicate to me that it's supposed to be a new one every round. (I think, I don't have the book atm, but thats how I remember it). Seems pretty boring if it doesn't. Anyway, we played it that I, as overlord, just discarded the top token at the end of my turn, but still showed it to the heroes. That gave them enough information to figure out which ones were left, but kept things interesting. And they only spawned 2-3 spiders or so (which didn't really impact the game, they never assisted Ariad and were killed pretty quickly).
Maybe that also should be submitted to FFG?
I do not think that is how it is supposed to be played.
At the start of each round, the OL secretly looks at the top objective token of the stack. If a hero enters an empty space adjacent to a faceup token of matching color, the OL reveals the top token from the stack, and places a cave spider on the faceup token.
For the rest of the round, the revealed token remains faceup in the OL play area...
...Once all tokens have been revealed, shuffle the tokens back together to create a new stack.
It doesn't say that at the end of 4 rounds you reshuffle the tokens- it says after every token has been revealed , meaning you do not cycle the stack/ remove tokens until a hero spawns a spider from the top color. The sentence in the beginning " at the start of each round " is only there to specify when the new top token ( if any ) takes effect. That is, it does not remain the revealed token for one complete round from when it was revealed, just until the end of the current round, and at the start of each round, the OL checks the top of the stack again. If the token is not revealed, it clearly stays on top until it is.
