When an imperative is achieved the "Proceed" button is missing. This results in the inability to continue in any way.
This most likely happens because of playing on 32:9 display. The resolution is 5120x1440. When scaled back to 16:9 the button is visible.
(possibly with any savegame file) 1) download and load the game file (savegame file is in log files because of size)
2) Change graphics to fullscreen 5120x1400 pixels (possibly any other 32:9 resolution) on fullscreen.
3) Unpause the game and wait for monument completion and
