Bug(?): Chat's getting out of sync

There’s time where I’m using DM’s and mesages appear to be sent out of order between both recepients. I dunno if it’s intentional so that’s why I added the “?”

Here’s a made up Example, P1 - Person 1, P2 - Person 2:
The original sending order:
P1: Hey, how are ya?
P2: I’m good! Just finished up dinner.
P2: I had a fresh slice of pizza to end the night ^w^
P1: Whoa that sounds amazing rn, what was on it?
P2: Oh just the basics, Pepperoni : P

P2: Not really a fan of most other toppings…
P1: Ah no worries, I usually order the Meat Lovers

What is instead displayed:
P1: Hey, how are ya?
P2: I’m good! Just finished up dinner.
P2: I had a fresh slice of pizza to end the night ^w^
P2: Oh just the basics, Pepperoni : P
P1: Whoa that sounds amazing rn, what was on it?

P2: Not really a fan of most other toppings….
P1: Ah no worries, I usually order the Meat Lovers.

I bolded the difference, but I don’t know if it’s just a ME thing but the person I was DM’ing also said the messages get mixed up from time to time when swapping tabs for a brief second.

I think it’s to do with the load on my poor server. We’re preparing plans to move next week, and we can observe if the situation improves then. If not, we’ll investigate.
