please change the ai of tfv countries so they manage to leave the allies before war breaks out if they choose to abandon the commonwealth.
While I agree I have to add: only in ahistorical mode and the chance being <25% except for with South Africa (more like a 50-50 thing there)
Really, I've never seen them focus-abandon the UK...They already only take the focuses in ahistoric mode. What OP is describing is that, when on ahistoric mode and a commonwealth AI decides to abandon Britain, they do not leave the Allies.
