Found a bug where Priests use Holy Warrior on mind controlled units. Specifically, the Warlock used Mind Control on a unit, the Priest used Holy Warrior on the controlled unit, then the Warlock used Spectral Army and broke the mind control. When that happened, my soldier had 2 action points, but couldn't use any abilities (like weapon, equipment, etc), only able to move around. I was told that the base game Priests aren't allowed to Holy Warrior mind controlled units normally, so could that be something that you add?

sorry bud, that not coming from this mod. I did not change anything of the Priest's Holy Warrior in this mod. Its using 100% base game Holy Warrior. And base game Holy Warrior does indeed allow Priests to target mind controlled units. So whoever told you that, is wrong sadly. Once a target is mind controlled it becomes a friendly unit so that mind controlled units can have Holy Warrior cast on it. The only exceptions per the base game code are these...

HOLYWARRIOR_EXCLUDE_TYPES="ChosenAssassin"
HOLYWARRIOR_EXCLUDE_TYPES="ChosenWarlock"
HOLYWARRIOR_EXCLUDE_TYPES="ChosenSniper"
HOLYWARRIOR_EXCLUDE_TYPES="Gatekeeper"
HOLYWARRIOR_EXCLUDE_TYPES="Shadowbind"
HOLYWARRIOR_EXCLUDE_TYPES="Spectre"
HOLYWARRIOR_EXCLUDE_TYPES="SpectralZombie"
HOLYWARRIOR_EXCLUDE_TYPES="SpectralStunLancer"

The priests seem to never fire their weapon nor Overwatch. They'll use all their abilities including the new ones, which are working fine. Just that when all their psi abilities are on cooldown, they'll spend both action points just moving back and forth. This is the case for all 3 tiers of the Priests.

I don't have any mods that specifically alters the priests' AI. The ones that I have alter some other existing units but not the priests.

thank you for the feedback, ill look into it now

Having the same issue as with knightmare047, priest just runs around not ever shooting after using his abilities.

To make priests shoot
Open XComAI.ini and add this line:

-Behaviors=(BehaviorName=RandSelectFromPriestAbilities, NodeType=RandSelector, Child[0]=TryPsiMindControl, Param[0]=33, Child[1]=TryStasis, Param[1]=33, Child[2]=TryHolyWarrior, Param[2]=33)

before:

+Behaviors=(BehaviorName=RandSelectFromPriestAbilities, NodeType=RandSelector, Child[0]=TryPsiMindControl, Param[0]=20, Child[1]=TryStasis, Param[1]=20, Child[2]=TryHolyWarrior, Param[2]=30, Child[3]=TryShootOrReloadOrOverwatch, Param[3]=30)
