There's an issue with the 'slave revolt' event that was kind of game breaking.
A revolt happened in my capital; I bought them off, it continued; I cracked down (lowering population); the revolt made my economy insolvent (the capital, the wealthiest city in most early games, wasn't producing gold!), so I couldn't buy them off again; I cracked down again, bringing my pop to 1; at this point I could neither buy them off nor crack down (can't with pop at 1); I clicked the 'hope it dies down, but revolt may continue button' -- it sure did continue! In fact it never stopped. After nearly 15 turns of revolt in my capital, I had to enter the worldbuilder and add some pop to the city so I could crack down again, which ended the revolt that time.
Not sure if this is WAD. 2 outstanding issues:
1) Early on, I switched away from slavery, hoping this would quell the riots, as, well...there would be no more slaves. Didn't work, slave riots continued. Surely this isn't WAD...?
2) I've noticed this happen to AI, too. In one game, I constantly saw the message that the Chinese authorities were 'bumbling the crackdown on the slaves' -- for ~30 turns. I couldn't see the Chinese, but this must severely unbalanced their neighborhood and possible lead to revolutions. And they can't enter the worldbuilder to add more pop! Again, this seems game breaking to me.
Sorry if this has already been reported! I scanned through & didn't see it. I was playing the latest build of LOR.
