While carrying the last of the Pending Deliveries, the jar of rosewater, through Glowecestrescire, the game prompted me to focus at something. I was at the crossreads east of Thieves Warren. There was nothing to see, so I put the jar down to examine what I was supposed to look at - I still do not know: a few trees, a patch of sky? -, but when I turned back to the place where I had put down the jar, it was gone. It was nowhere to be found. I tried restoring an earlier savegame from when I was sailing from Ravensthorpe to Glowecestre (with the jar aboard), but the jar was not on my ship anymore, so I have to start this all over again.
I might add that a few minutes earlier, I had also put down the jar because I had to fight off some bandit just north of Glowecestre. There was no problem then.
It is difficult to immerse yourself in a game that has this many bugs and crashes every few hours.
