I know that it isn't possible to start production of a Trader if you don't have enough Trade Route capacity, but what happens if I'm already producing a Trader when I lose the capacity?
I'd like to know if the production continues and if it doesn't, if the spent production is lost or if it carries over. Based on what I've read elsewhere, excess traders become idle and can't establish trade routes until the capacity is increased, but that's for existing traders and not for traders in production.
To give you some context, I'm currently running a Merchant Republic and I'm considering switching to Monarchy, because most of my cities are short on housing and most of them have walls.
