From day 23 to day 159 I had the entire frigging map revealed in the wilderness game mode, but after entering then leaving the cave in 1.05 it was completely gone and I never died in game or rerolled because of it so that's not the problem. This is really upsetting seeing as I had some huge plans for my world and it requires me having full vision of my map. If going in the caves is going to reset my map every time I exit it DST isn't worth playing until it's fixed (for me at least) so I'm just going to play shipwrecked.
Steps to Reproduce
I think the bug came with update 1.05 and if it helps I did randomly lose connection to the Klei servers (all good on my end) but I had my map afterwards until I went into caves got some light bulbs and my miners hat, refueled my lantern, started freezing made a fire and left the cave at the same time a new day was starting and the game was saving. Then I lost my map...
