Spider spawners not working?

[Ace0482]

So me and my friends are trying to do the Arachnid Exile quest to unlock the desert island but I don’t think our spider spawners are working unless there’s just a spawn time that I don’t know. Any help is appreciated!

If you place them it will take around 2 minutes to spawn. Other thing could be that the room is to small. Otherwise I don’t know the problem

Hey! As said above, make sure you're waiting a bit for them to spawn and if you're making a spider farm that the spawners are on the ground.
