Summary	0000098: [ZScript] Custom class properties referring to DECORATE actors cause a crash
Description	A custom property of type class<Actor> will cause a crash if the value of the property is set to a DECORATE-defined actor class. The crash happens as soon as an attempt is made to read the value of the property. I was converting a project of mine to ZScript and ran into this issue. Sometimes the value of the property was null when it was read, but in a test case I've made (and attached to this report) it doesn't happen.
Steps To Reproduce	Load the attached PK3, open any map and type "summon a" in the console. BOOM - crash. Tested on gzdoom-x64-g2.4pre-219-g4dc1d11.
Additional Information	If the property type itself refers to a class defined in DECORATE, the script will fail to compile. I have no idea whether it is a bug or a feature.
Tags	No tags attached.
