I titled this melee weapons bug however I only have had experience with the specific bug when using the Brännboll Bat.
Platform: Xbox One
Description: Me and 2 other friends are unable to do damage to enemies when using the bat. We attacked a dog for a solid minute with no signs of damage, including when doing a power attack.
Steps To Reproduce: Equip bat and attempt to use on enemies
Images / Videos: None
Host or Client: Had the issue as both host and client
Players in your game: Issue occurred with 1 and 2 other players
Specifications: Xbox 1 X and Xbox 1 S
I was unable to find another bug report and if it is in fact a form of user error then please explain how the weapons are meant to be used.
