I have made an atrocious, terrible mistake. Brief: I have done a lot of stuff after retreating from the shore (I wished to just reset "Power" as the game would suggest, but got carried away and did many achievements, quests and upgraded the mansion a few times). Version is .410
So, while in the mansion, I repaired the dungeon (I thought it is how you access ghosts to purify, kinda like in the fixed Fay Forest left from the entrance. I discovered a hidden (?) door there, went inside, discovered some shady dude on the throne. He said it is not time and put my party to sleep. The party woke up in the same corridor with the dude. I tried to approach him again. The voice line remained the same. I could not return to the mansion: if I exited the corridor, I would end up in Lilith's nursery (I guess. The fleshy facility with hanging women, spores and stuff in it). Pretty much anything I would do would lead to a crash. If I collect the strange egg I find right outside (Leah said "the guild wants it", although there was no such quest in the guild yet, only two quests, both completed: the bee one and the fairy one), it opens up path ahead (removes blue thing) and go up the corridor (forced to smell miasma all the way, although it would not cause anything: nothing changed, just an annoying message pops up, saying "spores bad"), it would block me, creating an obstacle (the same blue thing sprite, right as I would try to leave the corridor and go into a branching room.
At this point if I dare to open menu and then close it by pressing "X", the game crashes with the following message:
«Game has encountered a bug. Please report it.

Press F5 to restart the game.»
So, I have restarted game many times and found out other scenarios to get a crash exist. If you dare to inhale spores once: crash is guaranteed whereever you go: once you go into another location (the corridor, the pit, or you leave the pit by standing on the blue circle — the same crash. The message is the same, but on the black screen).
Finally, if you manage to never step on any trap tile, be it spores or the red circles in the pit, and you step on the blue circle: your party gets teleported somewhere else in Lilith's stronghold (she walks back and forth there, just a bit to the North), and your party gets stuck. The game forces them to go up, and they push against the wall with a girl inside it endlessly, stuck in this animation.
I really like the game to far, but I hope nobody suffers the same bug under the same conditions, you know how frustrating it can be, to lose so much progress after playing non-stop, enjoying the new game.
Thank you very much for the game, I hope you enjoy and have much fun working on it! ^^
