@Koochi-Q Heh, I can draw a parallel between what you say and bugs, to get back on topic. It's difficult to discern the causes for bugs, when it's servers side, when it's client side, when it's network side, whether it's something easy to reproduce and fix or not.
I'm currently looking at one of Apex's serious issues to understand how it happens, out of curiosity. It's the slow motion moments we get every now and then. I think this happens when the server fails to process a few ticks in time, so it forces the internal game time to slow down until it can catch up. This may possibly be a failsafe measure, server would probably crash otherwise. Wondering what causes servers to slow down though, could be suboptimal code that puts pressure, could be lower end hardware, too little maintenance. limited availability leading to congestion, etc..
