Bug In Gangplank's Barrel Charging mechanic

I've observed this bug ever since the champion rework came out-- And it doesn't happen often(twice every dozen games... maybe less).

However when it does happen, though, it can make GP pretty much a non- factor for a valuable amount of time.

The bug I am describing though involves Barrel casting interacting with the cooldown of his barrel:

When has a barrel queue'd ready to cast, well, it seems you wanna wait for another barrel in order to chain, however you planker you casted your barrel right off getting 2 barrels queue'd to cast------- BUT by doing this you've cause_ both_ barrel's to go on cooldown.

The reason i was able to catch this bug was because when the barrel's cooldown had refreshed after stalling, I was left again with _2 barrels _

I hate this bug so much and it costed me some kills that would've been instrumental to winning a game.

Edit**:

Keep in mind when you cast a barrel: ONE barrel does actually get placed
