Frequent disconnections

[Graptos]

Randomly in missions, I get disconnected from the squad and, when I return, the game is often broken. For example, in index, no enemies spawn again, and I'm not revived after I die.

The disconnection often happens when I experience a FPS drop, but not only then. Sometimes, without problems on the FPS or ping, I'm disconnected from the match. So far, I've lost many index runs because I simply couldn't gather more points without enemies spawning, I've lost arbitration loot, toroids from the orb vallis, had to re-do sortie steps...

The disconnections aren't always related to the ping or FPS, sometimes everything is ok and people are still separated, and I'm not the only one experiencing this.
