When reaching monkey village playing as Paladin (also as Fighter but I don't know whether the bug reproduces then) you're supposed to ask Manu (the monkey) to help you climb up. Specifically you're supposed to ask about help then about rope then about vines then about swing line (if I remember correctly). However when playing through ScummVM after asking about rope you can't ask about vine (it just lets you ask about rope again) so unless you have the magic user's levitate spell or the thief's climbing skill you cannot go to the village and therefore cannot finish the game. Attached it a savegame at that point.
