Game is indeed buggy. Issues I've found with settings, NTR on, and Yumi a slut from the beginning.
MC name is sometimes just "[1]"
Text boxes are broken, there's no right border, so the text is a single line that goes off the screen
Random bits of spanish when language is set to english (english also has some typos)
In Dania's shop, one of the counter tiles has no collision, so you can walk through it
If you reopen the quest board right after accepting a quest, the "Quest 5" option will be missing. Close and reopen the quest menu to fix
After first night in inn, opening menu in step father's bedroom is fine, but opening menu in the big room leads to a missing image error, needs restart. Menu works fine outside the inn.
If Yumi walks alone and encounters Navril a second time at night, game becomes a black screen, but you can reload
If you enter any of the inn's upstairs' bedrooms, you can't move or open menu. The in game clock still continues
The option to skip the east forest trail (goblins) doesn't make you jump enough tiles on the world map, so you end up stuck and need to reload
Farmer quest cutscene keeps re-triggering every time you enter the farm (maybe turning in the quest fixes this?)
