Any news on this issue? It is still present in 42.7.0.  

It is completely surrounded by trees yeah. It was also the day after I installed a generator, so I think you could be right. However I have been foraging in the same woods for weeks and didn't see any. Not sure how loud the generator is in b42, could it be they came from outside the forest/ the edges of the forest?    Thanks for your reply!

Are you able to make a Meat Patty using the Crafting menu? It should be an available option if you have ground meat in your inventory and are standing near a crafting surface. Once the meat patty is made it can be cooked, and with that you should be able to turn it into a hamburger.

Please, follow this guide:   

We are working on the fix!
