I got an error for the 5th (breeding) temple event, visit after 50 days:
Edit: if I then choose "ignore", I can proceed, but then encounter another error here:
Then again, "ignore" until this error:
There are others after, it's again the "KeyError: u'player_name_temple_class'", related I guess to the name of your character.
(I think I picked the first proposed name, "Ranes" I think. I had no issue until now).
My guess is: two variable in this event weren't written correctly, the character name variable and the "s5_envent5_temple_classintro".
Maybe you need to get rid of the word "temple", or "temple_class" or add "_" somewhere...
Edit: the "player name" error also occurred in the 6th visit (anal lesson)... And I just realized you posted about a hot-fixed version. I'll get it. (Not sure if it only fixes the first issue brought up earlier, or both, including the name).
Edit2: I got the fixed version, the first error is fixed, but not the second (the variable for the character's name, from the 5th even onward)
