Game save won't load in lobby after server crash

[Molean]

We were playing, suddenly the game crashed for a whole bunch of us, it seems the server went down and crashed all our games.

I tried to load a save of the previous game we were playing, but it wouldn't work, it complained of a missing WML child (see screenshot)

The save does load outside of the multiplayer server though.

And to specify, I mean the game crashed, as in shut down without warning or error. Not the first time this has happened either.
