Are you using the (current) version 26.01 of the game ?i have asked before and got no responce. is there a bug fix for chapter 25? i'm stuck at 77/121
And are you encountering a bug when trying to talk to Thea on OnlyFancy (or when trying to display the hints) ?
Because having the impossibility to talk to Thea on OnlyFancy can block the advance in the main plot: i.e. the concerned event with the bug is not important by itself, but talking to her on OnlyFancy is required to unlock some other events.
In this case, you could have a look at my patch for this version (only for the episode 25 in the version 26.01 of the game):
