Hmmm, if you could send me your save at unifoxgamestudio@gmail.com, that would be really great.
I don't get any problem with more than 100 character, so maybe it's something in your save directly, and I could resolve it, for the next release.
Also you could get the player log after a crash, it's located here :
"AppData\LocalLow\Unifox Game Studio\Nymphomania Fantasy Town"
Thank for the help :)
