Pet AI Duplicate Pet Summon Order Action Bug for SCH & SMN

Date & Time: 06/04/2020
Frequency: Always
World name: Leviathan
Character name: Nemekh Kinryuu
Retainer name: Naubi
NPC name: N/A
Monster name: N/A
Class/Level: SMN/SCH, any level with Summon Order Actions
Party or solo: Party
In-game time: N/A
Area and coordinates: Any areas with combat
Housing: N/A

Steps:
1. Perform a Summon Order action be it Whispering Dawn, Consolation, SMN Aetherpact or Egi Enkindles
2. Pet receives the pertinent Summon Order buff (Summon Order, Summon Order II, III, IV)
3. Observe the pet perform the resultant action after receiving the pertinent Summon Order buff
4. The buff is not consumed on this action being performed
5.a. Observe the pet perform the same resultant action again
6.a. The Summon Order buff fades from the pet
5.b. The Summon Order buff fades from the pet
6.b. Observe the pet perform the same resultant action again

This bug was reported when 5.10 was released during the time that if an AoE Egi Assault did not hit a target a pet would repeatedly spam their action and a Summoner would obtain a Further Ruin proc each time. While that has been fixed, the other aspect of the duplication was not addressed.

It's taken a while to commit to reporting this bug again because researching why it happens is a bit of a doozy. It is not something you can reliably make happen during encounters, although prepull some players have experimented with double devotion being more consistent.

What I am 100% sure of is that it is a result of the pets retaining their Summon Order buffs after performing the action which if still present makes the pet to perform the action again.

In the overwhelming majority of cases the timeline looks as follows:

1. Pet receives Summon Order buff
2. Pet performs the pertinent action quickly after
3. After a brief delay the pet performs the same pertinent action again
4. Pet's Summon Order Buff fades

Most cases I've looked at the pet performing the pertinent action has been effectively immediate (<50ms) with only one case having a fractional delay of ~140ms. This has happened for:

1. SMN Egi Enkindle
2. SMN Devotion
3. SCH Whispering Dawn
4. SCH Consolation
5. SCH Fey Illumination

However, in the case of Scholar there can be a queued delay after a buff has been consumed where the pet will still perform their action, typically with Whispering Dawn. This has always been the case where a fairy has had the following timeline:

1. SCH pet receives Summon Order buff
2. SCH pet performs the pertinent action
3. SCH pet casts and resolves Embrace
4. SCH Pet's Summon Order Buff fades
5. SCH pet performs the same pertinent action again

Examples where it has happened:

Unintended prepull double Devotion

Unintended double Enkindle: Earthen Fury

I do not have any clips of it happening to SCH handy, however, I know that it is a very frustrating bug for them when their utility is more time sensitive for a party's survival.

Please do something about pet AI, SE.
