Oh o_O I double check on my hand and it seems to work, I think the log, screenshots etc. would be helpful, I am sorry I will look into this as soon as I can
thank you, how could I send you the log? I've been looking for a mail contact and I can't find one.
Sorry our mail is contact[at]synstoria.com, can you also send the save folder? (game > saves) it might help too.
BTW, if anyone else, has the same problem, don't hesitate to share your logs, screenshot etc.
