Interesting idea, it might be useful to have some sort of index or inventory to go back to past messages! I found a message in a bottle, then instantly forgot what I am supposed to go, then proceeded to get lost hahaha. I also got the same "I should find the trader" message consecutively (I wonder if it's location based and I got out of the safe zone?) and it was a bit hard to move to get back on track ( I assume I was back on track cause it stopped lol)
