We have noticed an issue where the Tactical trait of equipment sometimes fails to work in the game. The bug is mainly due to some problems with the armor Reinforced Broadsider Suit (Assault) from Survival Pass season 10. 
 
Currently, we kindly ask all survivors to avoid equipping both the Armor (Reinforced Broadsider Suit) and  other assault weapons with Tactical traits simultaneously.
Swapping one of the equipped items may result in the Tactical not working in the next battle.
 
Our development team is working hard to resolve this issue. We appreciate your patience and understanding.
