Has anyone had minions double hit in their games?

This is a really shitty example, but it's been something that has happened to me for the last 1-2 months.

Lets say a minion has 50hp, and minions are dealing 25 damage per hit. The minion will lose 25hp but then like 0.25 - 0.5 seconds later it gets hit for 25 damage again and dies without actually getting hit for a second time.

There is a brief moment that the minion stays alive after it's taken the actual minion auto, but then dies RIGHT after without being hit again.
