Players have uncovered a glitch with the new Fortnite Chug Splash item where health is not granted in a particular instance.
Epic Games have been adding new weapons/items every week for quite some time now and the Chug Splash is the latest addition to Fortnite Battle Royale and was added in the v9.30 update that took place yesterday.
The Chug Splash is a throwable item and upon impact, players within the splash radius will be instantly granted with 20 health/shield for both teammates and enemies. Players can hold up to six stacks in one inventory space and can even heal knocked players.

Reddit user scatush has noticed that there is a glitch with the item as players that are using the Bush item cannot be healed by the Chug Splash at all. They have demonstrated the glitch in the video below:
You can’t get health from Chug Splash if you’re in a bush

You can see in the video that the player throwing the Chug Splash is being healed by it and the player in the Bush is within the splash radius, but is not being healed at all.
Epic are aware of this issue and have confirmed that they are currently working on a fix. Community Coordinator at Epic Game, u/M_House_Epic, responded to the post with the following:

“We’re currently looking into this issue. Thank you for pointing it out!”
We will keep you updated as to when this issue is resolved, but for now make sure you do not try healing players that are using the Bush!
