Blocked at the sniping the French guy, as reported earlier.
It is a loop, direct link = typo error, if corrected tough = infinite loop, after the water quest, this now...
As to inventory and bags, might be a way yes, but I've modded my save to have bigger inventory, so they are over 130 item inside by now, I could clean it a bit for sure (as I've several of not that critical items, but there is no telling if found again when needed later...). Inventory is somewhat tedious at this point but still manageable as items are either stored by recent add or later type. Not collected together, or best, bundled, as they are poisons over some bolts, where we use several arrows to craft one bolt (Balance I guess, still).
Tbs, but I guess the completed status should be removed, then see again after that update.
It's originally a Russian game btw, still plenty of it into several files.
