Hello guys!
Today a patch was pushed to Steam, fixing an issue caused by the Item Selector screen providing the wrong item to the system.
This can cause anything from incorrect amount of water filled in on containers, to - the actual reported bug - salvaging a Rabbit and ending up with Meat weighting 0 grams, causing the game to crash when displaying it.
This issue was solved on the new Content Patch. I thought I created that issue there, but nope, apparently it has been there all along. Whoops!
Restart Steam if needed for the update to go through.
Happy salvaging!
