True? No, it's undetermined. It depends on if the springs aren't of proper strength (for what they do). If this is an issue, we don't know yet.
The only people who have really made this claim, of it happening to them, say it about Hasbro beys. But if it's true or not, there's no real proof yet.
Avoiding keeping them assembled when you're not using them, storing them as separate pieces, is more of a "better safe than sorry" thing. Just easier to manage that way anyway, some feel.
