Looks like Epic just can't catch a break when it comes to fixing the Whirlpools in Fortnite. They have once again been disabled, so you can no longer take a spin and get launched up into the air and redeploy your glider to get around the map. Good thing we can hopefully expect cars to be on the way, because getting around by the sea is becoming difficult!
Here's Epic's official statement them being disabled:
As we address an issue, Whirlpools have been temporarily disabled. We'll provide an update when they've been re-enabled.
Whirlpools had been disabled for quite a while, and were only really added back in the Fortnite 13.30 Patch. The glitch they were struggling with apparently would allow you to get into a state of being downed and alive at the same time. You would basically end up in a sort of glitched mode, which allowed you to do crazy things like mess with helicopters and get under the map. This obviously causes quite a bit of an issue in the game, so Epic has been working on fixing it. It's clear that they are still having problems getting it completely removed, so for now it looks like whirlpools won't be working!
