Valuable Prisoner Taken toast description not stating name of prisoner in localization

[Rimaka94]

Issue Description:
This may possibly be an issue with a base game file. When the Valuable Prisoner Taken toast pops up, the name of the prisoner being taken is empty in the toast.

siege.1006.pow_toast.desc:2 "[occupant.GetTitledFirstName] took [valuable_prisoner.Custom2('MyCharacterIntroduction', ROOT.Char)] prisoner after the Siege of [barony.GetNameNoTier]"

game>localization>english>event_localization>war_event>siege_events_l_english.yml

How To Reproduce:
Go to war with someone (preferably a much larger target) and allow them to siege your capital until siege.1006.pow_toast.t:2 "Valuable Prisoner Taken" toast pops up, as can be seen in screenshot. If incorrect, this will not state the name of the prisoner that was taken, but correctly display their character to the right of the toast.

I can reproduce this as a Pygmy in Uldum as well as the Murloc ruler of Stonecairn next to Stormwind.
