Whenever I start a new world with Wigfrid, hitting the spacebar (either to skip the intro animation, or to start collecting resources), Wigfrid's action upon use of the spacebar is to eat the raw meat in her inventory.
I've been able to get around it by placing the meat on the ground before hitting spacebar at all, and picking the meat back up. This has solved the issue in each world.
The only exception has been my latest world, in which the meat problem was solved, however now she is changing her melee item whenever I hit spacebar. (If I try to mine with a pickaxe by holding the spacebar down, she's changing to the machete before any mining is done, meaning I can't hold down spacebar for any repeated actions.)
Load a world using Wigfrid, hit spacebar immediately.
