GP Barrel possible bug [GAMEPLAY]

Recently, throughout all of my gangplank games, I have noticed an issue with gangplank's barrels whenever I am below level 13, not too noticeable after. There are times where after placing down a barrel, I would auto attack it immediately, trying to reduce it by one tick, but the barrel just ends up exploding instantly. From my previous experiences, this should not be happening at all from levels 2~7 especially with low attack speed and high barrel tick timers. So far, I've noticed the issue in every game that I play as gangplank for at least a week, maybe even 2 weeks. It is also not a one time occurrence. It has occurred more than once in a single game before, sometimes consecutively. Not completely sure if it's just me or if this might be a bug with the recent patch.
