"KeyNotFoundException" when Delete Unused Components is On

[Yan-K]

I can successfully use Full preset with Delete Unused Components turned off, but when I try to create optimized copy with Delete Unused Components ticked, it gives following error:

KeyNotFoundException: The given key was not present in the dictionary.

I made it log a warning instead of crashing if this happens again. It might cause other issues though so keep an eye out for it.

Thank you so much! newer version works perfectly.
