Hi there Khaylis,
We’re so glad you’re finding the game to be interesting!
If you have the specific names of any quests and the stages that were not functioning correctly, please let us know here or in our Discord and we’ll see if we can help and/or fix the bug.
Given the game’s roots in classic RPGs, some of the quest notes are intentionally left vague or non-direct as to encourage the player to explore and solve the quest from the given clues - however if there is any wording you found too confusing or too obtuse (and as such made it difficult to finish a quest) then please let us know so that we can tidy it up and make it more accessible.
As for your question regarding certain character events - every non-temporary character event that results in them being removed from the party or changed in some way is avoidable and can be prevented by the player assuming they have met all prerequisites.
Thanks so much for your feedback, and thank you for supporting us!
