[Feature Request] Make Event Square have a 50% chance of triggering one of two options

[Deflaktor]

Add the possibility to specify two venture card ids to the event square. If the player then lands on the event square it triggers an event which makes the player throw a dice. If the dice is even then venture card X is played. If the dice is odd then venture card Y is played.

• The Description needs to be adapted too. This might be the most challenging aspect.
• Can conflict with #18

Wont happen anymore since it conflicts with #18
