Please fix the campaign progression bug!

Can you fix it already? Theres a big event in 4 days and part of the game is still broken. I cant even recommend the game to friends because of this kind of bugs, which made peope discouraged and let to the refunds of the game in the first place. At the beginning it was poor optimization, then crashes, then units being stuck EVERYWHERE, then blurry graphics and now a big part of the SP experience, that many people play before going MP, specially if they are new, doesnt work as intended. Please fix these bugs that werent even in previous patches already and let people buy and enjoy a game that doesnt make you play a campaign for 4 scenarios before you realize you can only send 2 settlers and a bit of wood through all the journey.
