For now i see that 10 Issues marked as fixed so when will we able to test?

I´ve three or four prisons and 2 of them near day 100 and no tunnel till now.

The other two have every 3 to 4 days a riot, many tunnels and also near day 100.

Try to let them work 1 or 2 hours more a day, less free time, less food and you will have riots and tunnels.
