Hi, I've been following your Game Tutorial and I got everything up and running until Part 18. The first Battle, wherein my game locks up after I select anything from the battle menu (attack, ability, defend, etc) and then select a target. I get the following error on the console.

NullReferenceException: Object reference not set to an instance of an object

This issue happened on two different machines independently following the tutorial, with the Unity version 2017.2
Thanks for your help in advance.

Yep, that's a bug, will be fixed in the next update.

In the meantime, you have to enalbe Use Attribute Changes in all Value Change settings of your abilities and items (e.g. in the Base Attack ability you'll have to do this in the target changes and critical target changes).

Thanks a lot for the reply! It worked just fine.

If you don't mind me poking you again, is it possible to switch the player combatant from combatant A to combatant B through an event? I'm trying to have a different player model once I enter combat and then go back to the original one once combat is over.

Thanks again.

So, not actually changing the combatant (which would be possible), but just showing a different prefab?

Check out the Conditional Prefabs in the combatant's settings for that :)
