I found two bugs in the stress test today.
1: Take a shovel into your hands and start digging out a worm. Then swap the shovel with the worm and eat it or throw it away. Then try to take the shovel directly to the hands up from the ground, it wont work (You have to take the shovel first in your inventory and then in your hands).
Update: Its also working with just trying to take the shovel from the ground directly into the hands.
I could reproduce this bug several times.
2: I somehow bugged my weapon cleaning kit away when I tried to swap it against a rifle (dont know the type anymore, maybe a carabiner or a Sporter). After that I found under myself two papers in the midst of the street (I didnt had any with me).
I only tried this ones because my cleaning kit bugged away
