They sold most (all?) of their studios (for example Black Sea was sold to Sega) and I've read about investors. Rumor has it that the Lumberyard deal was already used up earlier this year which seems to be the reason for the alleged salary problems (that also happened before the Lumberyard deal in 2015). But who knows.

I wonder how their business plan is working out for them, as the engine is completly free (if you want, as the engine is pay what you want) and unlike UE4 has also no royalties.
