how come settings keep changing to default when i want to play cba hero i just want to start the game and not have to change anything

Which settings are you talking about? Do you have a screenshot? Please also add technical details: which patch, which map version etc.

for cba hero i always have scenario selected as CBA hero v52 map as explored population set to 250 and difficulty as medium I am on 1.0c by the way but eveytime I load up next time the settings change that I have changed change back to default

You must play the map on patch 1.4 RC or higher.

Confirmed happened to me even on v1.6 Custom Scenario kept reverting back to map unrevealed which never used to happen.

Screenshot please? And more details on how to reproduce the problems please. Thank you.

Keeps reverting back no Normal, when it used to always stay Explored.

I just tested setting the game fast with explored map, launched the game with me and one AI player. Let it run for a bit. Closed normally and when re-launching the settings were still fast and explored.

Yep seems it stays now for me too now but I swear the last 5 to 6 times it would go back to normal.
