PC, Steam, 1.6.15
A user reported this one on my mod page, though I was able to replicate it with only debugging mods installed. There seems to be an error with the "Evelyn_love_AfterMovie" response in MovieReactions.zh-CN.json and its tokenizable string, causing the dialogue to appear in-game as shown in the image. I also included the error thrown.
[game] Failed parsing dialogue string for NPC Evelyn (key: , text: 真好看……现在你该知道为什么《System.String[]》算是经典了吧。).
IndexOutOfRangeException: Index was outside the bounds of the array.
