Summary0000231: Trying to use null in Class<Actor> property causes crash
Description
Class<Actor> OldMonster;
    Class<Actor> NewMonster;
    property OldMonster: OldMonster;
    property NewMonster: NewMonster;
    Default 
    {
        D4DMonsterSpawner.OldMonster null;
        D4DMonsterSpawner.NewMonster null;


This will cause a crash at start-up, though it shouldnt. While I can simply just not use what's in the Default block, if we want to have another inheriting actor wipe out the old/newmonster properties, using null will cause a crash.

The last thing it reads before the crash is "Cannot convert to string".

Crash is fixed in d2affc7.
'Cannot convert to string' error is still here, I'm not sure how this should work to be honest.

Most likely there is no need to add anything to Default in this case. Those members will be initialized with null anyway.

 The main problem is inheriting from an actor which it's defined in and I want to get rid of the definition. I.e. they have a Zombieman and I want it null in the child of the class that has said Zombieman defined.

I cannot say for sure why null doesn't work (i.e. is it intentional or not) but "None" does.

I believe the given assignment doesn't work because it's impossible to assign null to a string variable in general.

All this stuff hasn't received any real testing yet, I was planning to do that after scriptifying the menu and export as many actor properties as possible to the custom system instead of hard coding them in the engine.
