Title: Variable crashes Playmaker - Argument cannot be null
Post by: adgrist on July 18, 2014, 06:22:34 AM

Having noticed that an element of our project is not working correctly, i noticed that a variable had just been set to 'none' in all the actions where it is used. When checking the available variables, it turns out it still exists, but when clicking it, playmaker has an exception. This is an Object variable

Any ideas what has caused this or how it can be fixed?
