If statement executing even though argument is false
I have a function to check if an inventory slot is available, but the if statement has begun executing even if its argument is false. This only started happening after I changed some stuff before this function is called from another class, but nothing witthin this class itself. Am I missing something obvious or is my project cursed? 
Are you sure both objects are null? Better check with debugger. $$anonymous$$ight be that they are not a nullable type (for example Vector).
Oh completely misread. Try hovering over the item and parentSlot values in the if statement. Sometimes VS doesnt update watches.
Well we don't know much about what item and parentSlot actually are. I never really tested this in the debugger but it might be possible that the watches VS is evaluating doesn't use Unity's overloaded == operator. So if your item and parentSlot references are of a type that is derived from UnityEngine.Object, technically they might not be null but both point to objects which have been destroyed / wrongly created. The overloaded == operator would fake that the objects are null in that case. This could be a bug in VS
If you have never heard about the custom == operator I highly recommend to read this blog post. Even if you already know about the == operator but haven't read the blog post yet, I still recommend reading it. It's a fundamental part of Unity to understand the two sides and how they interact with each other.
Note that this is just a guess based on what we can see in your question.
