[GAMEPLAY] Death timers and respawn time not working correctly

I checked in replay but at 20:07 in a match I played as casseio my teammate nasus dies and gets a 36 second respawn timer. Then at 20:08 I die and get a 40 second respawn timer. Immediately after this nonsense my other teammate olaf dies at 20:10 and gets a 34 second respawn timer (at the exact second he does I am still at 38 seconds). This was not a replay glitch as Nasus then spawned, a second later olaf spawned, and then an entire 3-4 seconds later I spawned in. I found this very strange to the point I even doublechecked if the olaf had respawn timer runes (he didnt) .

I wouldnt normally care either but I realized this was right as the enemy team ran over to start a baron and most of the gold on my team was on me. My delayed arrival of an entire 4 seconds easily couldve been the difference between a baron rush or no baron, which can easily cause a win or a defeat and it was in a ranked game to boot. If you would like the replay as video evidence just ask and I should be able to provide it.

I died a second or two before someone on my team and they respawned 4 seconds before me.
