All NPC chat boxes suddenly became blank / empty - cannot quest or progress

[Geryth]

Looks like it's exactly this same issue:

I'll try switching language to see if it helps

Edit: Confirmed that switching language to Japanese advanced the quest. Hard to navigate in a foreign language but it was enough to get me going. Definitely needs to get fixed.

I talked to Emmanellain and Honoroit who were the next quest objectives. They babbled on in unintelligible Japanese and I nodded through the chat boxes. I then logged off and set the language back to English. The next quest objective was Laniaitte, whose chat box was also blank, but the proceeding box was filled in with the quest rewards. I took the reward and now the next quests seem to function properly.
