The script \A3\Structures_F_Exp\Infrastructure\PowerLines\Scripts\column_ruins.sqf gets execVM'd in the killed event handler for multiple objects. This script does NOT have an isServer check, and will execute a setDamage for every player as well as server.
Essentially it is causing duplicate setDamage across the network where it should not be.
Every object that has this issue is as follows:
[
["Land_PowerLine_01_pole_junction_F","[(_this select 0)] execVM ""\A3\Structures_F_Exp\Infrastructure\PowerLines\Scripts\column_ruins.sqf"""],
["Land_PowerLine_01_pole_lamp_F","[(_this select 0)] execVM ""\A3\Structures_F_Exp\Infrastructure\PowerLines\Scripts\column_ruins.sqf"""],
["Land_PowerLine_01_pole_lamp_off_F","[(_this select 0)] execVM ""\A3\Structures_F_Exp\Infrastructure\PowerLines\Scripts\column_ruins.sqf"""],
["Land_PowerLine_01_pole_small_F","[(_this select 0)] execVM ""\A3\Structures_F_Exp\Infrastructure\PowerLines\Scripts\column_ruins.sqf"""],
["Land_PowerLine_01_pole_tall_F","[(_this select 0)] execVM ""\A3\Structures_F_Exp\Infrastructure\PowerLines\Scripts\column_ruins.sqf"""],
["Land_PowerLine_01_pole_transformer_F","[(_this select 0)] execVM ""\A3\Structures_F_Exp\Infrastructure\PowerLines\Scripts\column_ruins.sqf"""],
]
This was an issue with other objects from a previous update, but has since been fixed for reported objects - https://feedback.bistudio.com/T196391
