I actually added an "in-run" blacklist to this on my last run after it fueled my car with my glasses of goat's milk (Too lazy to use the "this item only" functionality to get my fuel - nice to see you improved that some). Out of run, I don't care if it uses goat's milk.
Would you consider adding an "in-run" only blacklist in addition to the overall blacklist ? Else, it appears to use your blacklist would require clearing and rebuilding it as game states change. Not a big deal if you're not interested, since my local copy already has this ability. Just thought I would throw it out there.
