How do I find a thing replaced error??

[Freewolf]

So I had created a spell package that is replacing some versions of spells. It was working just fine.

However it seems after the last update, one of the things I am replacing is now being replaced by something else.

So now I am getting Thing to replace is already replaced by another thing and cannot be superseded. However I am not sure which thing replacement is causing the error now to debug and fix it.

How do I go about discovering what is causing the conflict without rebuilding everything??
