Multiplayer respawn attributes sometimes resetting on editor reload

[Maurdekye 10]

I enabled Respawn on Custom Position and checked the Choose Position checkbox. But when I started the mission, there is no respawn selection gui and the box is unchecked when i go back to the editor. This bug occurrs very inconsistently and seems to pop up and resolve itself autonomously between reloads of the editor. It can happen to any given mission. At most it's a major annoyance, but i'd like to see it fixed eventually.
