It's the I-patch! Read the forum and you will see that we've had a rather detailed discussion over the ineffectiveness of the patch over the last 24 hours or so.
The patch needs updated every time the game is updated. That isn't happening. If you DL the game and replay from the start with no patch you should have zero errors. I've already proven that to myself. Give it a go or don't...
Adventure ever on, Phat
I do not have the patch installed and i'm having the same problem in the threesome scene... Already restarted the game from the beginning 2x and the problem still persist...
FIX FOR RONDA MARIA THREESOME:
Well somehow i managed bypass the problem just editing the rondamaria.rpy in the game/events/maria, to do that i had to use the Unren to extract and decompile the game files, after the message sexuality increased
the game jump to player room instead of doctor room, go to sleep and you will receive the maria message,
idk if this will break some variable but my game still normal untill now of course, if i had some problem in the future i report back here, its a temporary "fix" to this problem... (Sorry for my broken english)
Label fixed properly, thanks to the info MisterDan.
Finished the game without problems.
How to fix:
1 - Put the the UnRen into your game folder
2 - Execute and choose the option 1 wait untill the process is complete then choose option 2 and wait untill complete
3 - Go to game\events\maria and put the rondamaria.rpy there (REMEMBER TO BKUP THE FILES BEFORE REPLACE)
4 - Enjoy
