Loving this game so far. I just finished act 3, and I have a serious bug to report. If you don't perform the actions in the correct order in the final level, you enter an unwinnable state where Morglot is never marked as completely "happy", even though you have performed all the required actions. I restarted the level and went through it a lot more efficiently and "in order" the second time around, and then it works.
I encountered this problem too.
I tried this act a couple of times. I did finish it today, doing the same things I did before, just skipping dialogues and in order.
I think the problem was with Frippone - I'm not entirely sure, but I think I didn't get the last dialogue, about sitting on the bench.
I think previously I did not do the things related directly to Morglot's problems in order. I can try to reproduce it, although I don't know if I can retrace my steps.
Hello Pierre! I ran into the same problem now for the 3rd time (after starting the level all over again), where Oups says young Morglot's problems are now solved but if trying to wake up the adult Morglot, then Oups says "Before waking him up I think I forgot something...".
I have done all required actions with other children but apparently I don't know what is the "correct" order. When young Morglot asked Frippone to sit with him (before using the slingshot on a snake), she declined and now Morglot never asks again.
I gave teddy bear to Frippone before Morglot had used slingshot.
