Damn. Such a random absurdity simply cut off a piece of content (trader with his useful goods at this stage and the reward for saving Rugan and Olly). Of course, I sent my save file to tech support, but I am afraid that you will be right, and nothing can be done here.
Usually I periodically made a backup copy of the save (in "Divinity" on max difficulty, for example, so that I could recover from critical bugs), but here I hoped - to my misfortune - for the game to be a full finished with a perfect technical condition. Alas.
Thank you for your answers, anyway, and have a nice day
