Reproduction steps

1. Be an engineer profession and have a pet out.
2. Send pet to attack an enemy npc.
3. Before first enemy dies, tell pet to attack a second enemy.

Expected results

After pet is sent to attack the second enemy, damage numbers should float over the second enemy, also second enemy's health bar should be updating (decreasing as it's being damaged).

Actual results

Damage numbers are still floating over the first enemy and its health bar is decreasing. When I open information window of both enemies, they health updates with the server so HP bar of first enemy jumps to full and HP bar of second enemy decreases as intended.

Bug prevalence

Every time.

Description

So, switching my pet's target updates on the server's side but on the client side it seems to be still stuck on the first target. Client starts updating health on the second target only once the first enemy dies.

Confirmed. The bug is reproducible as described above. The client incorrectly shows damage on the first target while the server correctly applies damage to the second target.

This can also cause the target to not die properly.

Added a video. You can see health going down on both targets health bars after pet target is switched. When the new target dies, the per leaves combat and the original target's health stops visually decreasing. After switching target back to original target, if the visual health drops to zero, but is not actually zero, it will jump to the correct health displayed.
