I ran into some error. I tried to copy paste the log but it's too long for that comment chat thinggy. Here's the last entry though :
File "renpy/script.py", line 900, in lookupraiseScriptError("coud not find label '%s'." % str (original))
ScriptError : could not find label 'chapter_wife_3'.
Error happens with both Ariel and Alesto at day 6
Some similar error happen with Renita on the night between day 3 and 4 while going to sleep
File "renpy/script.py", line 900, in lookupraiseScriptError("coud not find label '%s'." % str (original))
ScriptError : could not find label 'chapter_son_3'.
I may add that in both case i took the housekeeper background.
Hope that report helps.
