The fixtures are up already. We are starting the T20 Smash tomorrow.
Why mid season?
There are limited options in T20 simulators. CS09/15 isn't a preferred sim for most league managers (for various reasons) and Cricket Heroes:Local leagues is a paid sim. I tried getting a working Heroes:Local leagues setup before the start of TPCL with various versions, but faced many errors which led us to abandon it. I continued trying to get it to work and managed a couple of weeks prior to mid season break to complete a entire TPCL T20 season without any issues..
The inclusion post mid break is a surprise for the PC players. So kick back and enjoy
