People, save! Hanging unfulfilled order for return of acid bottle (Order: Side effects). It so happened that on the way to the post office, a notification about a new order (or a quest, or the sale of a car - I don't remember already) jumped out and I switched to it. After a long time, I found in the magazine that I had not yet fulfilled the order for the return of this beta acid. I come to the desired post office - and that's it, there is no hint "Press F to hand over the order"!!! Going into the post office itself - does not show this bottle in my inventory. I just look in my backpack - there is a bottle! What to do, how to pass the quest?!
