Spawning as Excalibur and then Evolution Engine Crash

[HeartlessFinale]

I recently started to play with other people online heavily to take down the jackal. I've found then in some games when i spawn I end up being in the excalibur frame with no skills set in, standerd hp values and a bronco equiped but cant really do anything(shoot, slice, but can walk). After a bit of time I am randomly teleported soemwhere in the map as my normal warframe (I'm a loki). After this happened the second time the evolution engine crashed with this message under details.:

Assert in BaseClientFramework::LeaveLobby(): (mServer->IsLobby() || mClient->IsInLobby()) [baseClientFramework.cpp:235] in 00000001400247CE() [????????.???:0]
