Basically it's just freezing the springs, making the springs stop at that tier and not being able to use it again unless you activate/unfreeze it.I'm sure some people know the pain of redoing a month (or more) worth of springs action again.
And it'll be nice to take a vacation without having to worry about hopping on just to use the springs, when it's not possible to get on the computer.
There should be like 3 or 5 freezes per account.
I don't think there should be tokens for it though.
I'm probably overthinking how it can be kind of abusive when someone buys up all the freezing tokens.
But I don't know.
