Dying and Losing XP due to fundamental issues with game performance

The game frequently crashes and either forces me to restart/relog or disconnects completely. This is usually not a problem, except sometimes it crashes the game while not 'pausing', which allows for my character to be killed while my screen is crashed or frozen. This problem has existed since the beginning of 0.3.0, and I no longer play with friends since it guarantees the game will not pause when I am crashed.
Just today, I deliberately attempted to pause the game, only for the game to tell me I have died, which causes me to lose hours of XP progress (level 99). If it was my death due to my own skill issue, I can accept, but dying due to game performance issues when I have lowered performance settings to the minimum already is frustrating
