Andor's Trail

With new version Bernhar has gone. I think I talked to him once (v.8.7) before I entered the cave going for some items. Today no one was standing there.
Hope this doesn´t mean my "preleveled" universal character is now coruppted

You have one chance with him.
¹ buy the items and he leaves

² interaction with him without buying.
Either way you have one chance with him

So I messed up.

But I´m quite sure I reloaded after any interactions.

There´s no way to see if i talked to him fully or not i gues?

Reconstructed it with an ancient save. I ignored Bernahrd completely, walked into the cave till the lowest area with the boss. Returned back and he had left.
Only question left:

Bug or feature?

Feature.
