Play/Sim Button not work

[Leonidas]

If you want to "Sim to a Date", choose this option and then choose a date, the "Play/Sim" Button will change to grey, so you can not more click on it.

Steam v9.4


PS: Using the "right" key on the date can give you massive Javascript warnings.

[Gary Gorski]

To do sim to date first choose the date, then choose the sim to date option - this should generate a popup in the upper corner saying you are scheduled to sim to X and the play/sim button should be active
