I was playing around with the Transition Adjacency Multipliers and encountered a strange error:
My entry in Transition adjacency settings is:
Transition Group: Fire; State Attribute Type: Invasives; Neighborhood radius: 500 m; Update frequency: 5
And in the Transition adjacency multipliers I have an entry like:
Transition Group: Fire; Attribute Value: 0.1 Multiplier: 0.7
This works fine. However, if I add a second line to the Transition adjacency multipliers (eg. Transition Group: Fire; Attribute Value: 0.5 Multiplier: 0.9), the Simulation will not run.

I have used several different values for attributes and multipliers, it did not change anything.
Is this not the way the Transition adjacency multipliers are supposed to work?
I would prefer to use the adjacency multipliers over the spread distribution, because it is a very straightforward method.
Thanks for help,
Thanks for your message. This is a bug which we will fix in the next release. In the meantime, there is a simple work around, just add a record with a multiplier for attribute value of zero. For example: Transition Group: Fire; Attribute Value: 0.0 Multiplier: 0.5
