This is NOT about changes to the gameplay effects of the cards, but other changes to the pre-existing storyline.
I've had in mind to post about this for a while, since it would have gone under the radar for a lot of people, but some key details in the AST storyline were altered with the 4.50 patch release and it was never really announced beyond a line in the patch notes about incorrect dialogue being updated.
A while ago I'd made a post in the Lore forum about inconsistent information across the AST quest, lorebook and other in-game references, which ultimately got an official reply from Fernehalwes (ie. Koji Fox, head of English localisation). Some key details were mistranslated and have now been corrected in the game script.
This might lead to some confusion for people, since any further quests will rely on that rewritten information as if it's always been there - and with the recently announced changes to AST gameplay, it's likely the script will get reviewed further, and if people replay it they might think the other changes happened at the same time or unnecessarily as a result. So I thought it's important that people should get a 'heads-up' that it's happened at this point, and why.
Key facts now altered or clarified:
The backstory events in Sharlayan happened fifteen years ago, not 'almost twenty'.
As a result, Leveva is 16, not 20.
Jannequinard is 32, despite some (now-edited) in-game lines implying he is older.
The count only has one son, currently 'missing'. Jannequinard is the count's nephew and third in line to the countship, after another cousin. (Also Forlemort is not strictly Janne's uncle as in "parent's brother", but in the broader sense of an older relative.)
Outside the AST quest, but corrected as a result of the same discussion - Mordyn is no longer incorrectly implying that Carvallain is married.
