The all-socialist government that's based on the soviet is (understandably) quite janky. I was playing as (internationalist) SR, and as the soviet government was formed I walked out. Nonetheless, not being a part of the Soviet Executive or the Provisional Government I could decide the governments answer to the peace offer from the Central Powers.... After that, I formed a new Soviet Executive with the Bolsheviks, got _all_ the ministerial positions, but there was no 'Provisional Government' deck on the main screen, I could implement government policy only through advisor actions.
