Hi Scott,
Try following:
- a task changes a numeric property of any device using a substitution string
- change this property now manually to a different value
- let the task change the property again to a complete different value (same substitution string)
I see now in the property's history the first change, which was done by the task, to the new value instead of the initial value.
I didn't try this with alpha values. Using 3.01
