Problem On Void And Assasination Missions

[laharl897]

so far I've unlocked up to Saturn on the planets. and the only assassination mission I've been able to play is Jupiter-themisto. and any void mission I do wont work either. here's what happens: first I pick an assassination mission and then I load it up. as soon as lotus gets done telling me our objective the game lags up and crashes. on the void its as soon as the scene pops up in the beginning where you break the vent down and hop down from the ceiling the game lags and crashes. it also tends to lag up immediately if some one has a kubrow with them in the assassin missions. none of this was happening before update 14. so I'm pretty sure its fixable. so please fix.
