Seen this last patch also but dint connect to what was causing it also no big as of the dc boxes. But as the pf if you use assault jump on anything that is not meant to be walk-able path the game will show everyone lagging and can sometimes lose people during this. Oftain what will happen also is the game will stop loading the next mission trigger so the next mission never comes (seen this happen for no heli coming and eggs not triggering after such a spilt.) A few spots I seen this happen at is the purple crystals above the airlock on both of the towers you stand on the hexes at in EC. But anywhere i tried that a unit is not normally meant to be able to walk to seamed to cause it.
