Need help. The Heli on the server can harm the Buildings of the player

[TruePVE] WARNING - invalid flag: 'NoHeliDamageBuildings' (does this flag still exist?)

"heli cannot hurt buildings",

I'm not sure how to set it so that helicopter gunships can't damage player buildings

thats not a flag, and you can't use rules when flags override them

NoHeliDamage
NoHeliDamagePlayer
NoHeliDamageQuarry
NoHeliDamageRidableHorses
NoHeliDamageSleepers
