Steps:
1. Call dragoon pet by using call wyvern and use the /checkparam <pet> command to see initial status values.
2. Level up dragoon pet by either killing enemies within zone for experience or using spirit link ability and use above mentioned /checkparam <pet> command to confirm status parameter increase.
3. Spawn a Geas Fete NM, such as Vyala in Escha - Zi'tah, but the issue happens on every Geas Fete NM.
4. Use both /checkparam <pet> command and <pettp> commands to view wyvern pet status during combat. No change in status values is experienced here and everything behaves as expected.
5. Upon successfully vanquishing Geas Fete NM, both dragoon pet level up status and accumulated TP are reset to initial values. Confirmed by using /checkparam <pet> and <pettp> commands.
6. Re-using spirit link ability will level up dragoon pet again and give proper in-game message, which confirms the reset status values. Spirit link ability recast timer however cannot keep up when Geas Fete NMs are defeated and spawned again in quick succession, resulting in Dragoon not being able to benefit from parameter boosts tied to wyvern parameter boosts, because these are reset every time NM is defeated.
