So this bug is pretty known among every Timmy, but now looking closely I could notice the same bug happening with a Robo Bebe. The projectiles of any ranged unit are pretty small in comparison to that of Timmy, on top of that Timmy has really low attack rate, so a change in it can easily be noticed. Well, you probably had this bug happen with any ranged unit, you just didn't notice, and why stop there, it probably happens with every unit in the game, not just Timmy or ranged units.

You guys may want to categorize this as a lag issue, when I had these bugs happen to me the gameplay didn't show signs of altered motion or delayed actions. But the full server side is being worked on right?, so issues provoked by lag shouldn't affect the gameplay in this manner anymore. On the other hand, if we do see them after that then there's something else happening here. I have a more paranoid theory of why these events occur actually so I'm just gonna throw it here, I think these little improvements to your enemy happen when matchmaking really wants to cut your win streak, so the game tries to help the enemy by resorting to this almost invisible and unnoticeable tactic. I've had matches before where I predicted the outcome of a small clash between units, and then the outcome was different, even though I was pretty sure of the prediction. Did double melee attacks happen there? I don't know...but now I'm pretty sure double hits are a thing for every unit, and not just Timmy's, let's revisit this once we have Full server side, I really want to believe developers don't resort to such tactics to keep users at bay from climbing too easily without buying stuff.
