I think there is some sort of lagging/syncing issues happening. Myself and others have noticed mechs rubberbanding, HP not being depleted when they are hit, mechs being invincible (Check Kax's video 2:10 timecode), etc. Your issue might be due to these.

Noted. I'd inquire on this matter.

I made an observation earlier in the topic "is the game facing a problem registering assists?" that might be relevant. It seems that even if you damage a mech, if it had mods and you first had to destroy the mods, then the assist is not usually registered. It's not consistent so there might be other factors but it is very frequent.

This is a real issue. Most of the times, you have to be actively killing the mech at the same time to get an assist. I have take so many mechs down to 10% health, only for them to get away around a corner. Someone esle will finsih them and I get zero assist. It is broken 

i was initially surprised tjat they managed to get a working system for kills from behind, escape enemy with ability etc etc etc really impressive. but the longer i play the more i realize its very bugged.. so many things dont work and you start noticing that when you either start counting yourself or start to care or its particular weapon, like assault weapons from behind.. idk it feels like 50% are not registered. But maybe its more like a latest thing.. and everything is bugged and out of sync.. as i killed first mech in FFA, didnt get point for it, but sign appeared saying FIRST BLOOD :) i think they heavily messed something up in last month or so

That is the old bug, you get the kill, but it doesn't count it properly until the game ends. You'll notice you have more kills in the end. The assists not registering is an ongoing issue and hurts your rewards, especially if you're chasing achievements or playing a tournament where every kill and assist count 

interesting i will keep it in mind..
