So I had just recently got Kerf - O for the first time on 0.8.2 and so I decided to bring it over to the new game through the mailbox. Im not sure if this is a manufactured bug to prevent people from bringing it over from the old save, I dont know if the recipe changed or if its become harder to get, and so its been intentionally bugged to prevent one from bringing it over or not. To my understanding that is not entirely beyond the realm of possibility.
However! If that is not the case, then there is an issue where Kerfur - Omega will not hold the floppy drive you give it, and instead will throw it away mere moments after it takes off to get reports.
Additionally, the "fix transformers" functionality might also be broken, as when I tried to see if it would do anything, I didnt get any kind of errors, where previously I believe it would say could not find or no transformers broken or something. Not 100% sure on that currently, as I've not had them break yet.
All that said, I think the changes are rad, just takes a little getting used to.
Edit: I also noticed a bug, when typing at a console to sv.target golf the F key turned on my flashlight. I assume that whatever code prevented input events from being triggered while looking at an object is also what prevented that from happening before. And since now we can interact with the controls while looking at objects (Such as middle mouse click to bring an item into your hand) I assume that got accidentally removed, now allowing for accidental inputs while typing.
