Whenever I use the shrink command or a shrink potion, if the target is not a BaseCreature the server crashes. Here is the Crash Log . Anyone able to show me how to fix this? I know I need to setup a null check if target is not basecreature, I just have no idea how to do it, least not successfully..
Here is the ShrinkCommand Script that gets referenced for targets
Code:
System.NullReferenceException: Object reference not set to an instance of an object.
