Miners trained instantly

I've put 400 workers and 100 miners on training, and miners have been trained at the moment, instantly, not wainting one turn at least

was it at or close to the 15/45 minute mark? I have put units into training at say 2:14 & by the time I click the button, they are trained, if this is not the case then it is something else, lol...

king's right, training works like income, it's simply not done at the 0/30 minute mark but at the 15/45 minute mark

you can increase your income by 500% and you get the new higher income even if only 1 minute has passed
