Ok, I have reloaded my old saved turn, i.e. the submitted turn minus all Messages. I have added the two declarations of war to be able to shoot back against the True Republic and the Aether Lords, and my cloakers to engage (which they also didn't as I noticed), and to enable my mines, and to correct whatever also might have happend (it might even be possible that they still got my minerals from the trade while I did not get theirs).
I tried to rewrite the Messages, but might have missed something - in that case, anyone who wants please feel free to answer to the message that came in with the old turn
