It's easy to have this happen if you encounter packet fragmentation, e.g. sending a packet larger than routable MTU. It isn't exactly rare if you're sending nontrivial amounts of data.

Oh ok i see, i'll account for this, thanks.

My guess is you simply haven't been paying attention.

Relax big boy, there's no reason for personal attacks, you should know that.

I don't think "I guess you haven't been paying attention" is an attack in this context; my apologies if you read it as such. I merely meant that you don't see these things unless you explicitly look for them, but once you do, you will see them with some regularity. If you're not explicitly looking for merged packets, you will "only" see "something weird" which you'll have no way to investigate (if you even pay attention at the time it happens.)

How about "I guess you haven't been explicitly looking"?

That sounds much better. You may want to be cautious with your phrasing, because "My guess is you simply haven't been paying attention." infers the other person was too lazy to notice something.

I accept your apology. I don't enjoy calling random people out in a gaming forum.

Dude, you need to grow a thicker skin.

Especially on the internet it's a bad idea to assume people are malicious with their wording. All we have is text, and human communication is far more nuanced than just the verbal layer.

Nobody attacked you, nobody insulted you, and you have nobody to "call out."

Let's not gang up on me now, I already accepted his apology,
