• Description: My game becomes completely unresponsive (can't perform any action, next turn & save don't work either, pending forever instead). This is my second game in a row with this issue, both time pretty late in-game.
• Version: 1.5.10 S5 GOLD-Public
• Notes I've tried workarounds suggested in other posts (reloading previous autosave, save & reload), but they don't work for me.

Same issue, can't get past turn 219 as Sophons. The UI as a whole stays responsive, but I can no longer take any actions in the game. If I try to end turn it stays as 'Pending', saving and loading are both also impossible - in fact if I try to save, the game gives me no option but to CTRL-ALT-DEL, as the menu options to exit the game become greyed out.
