[2020] Terraria Switch - Need some bug info!

I bought Terraria on my Switch recently (I’ve already played hundreds of hours on PC, but I wanted a portable version).

Long story short, it’s been great fun so far, and I’m about 20 hours in, BUT, I’ve just encountered a very frustrating issue. I’ve finally made the journey to the edge of my (large-sized) map, and whenever I reach the halfway point of the ocean (thereabouts) at the edge of the map, the game crashes.

Just a straight up, ‘game closed due to unknown error’ crash, and when I start the game back up again and reach the same point, it crashes again. It’s not a storage issue or whatever, because there’s plenty of space left on my micro-SD card.

Is this a known issue, and something they’re actively working on? Or is this some sort of rare thing that I’m getting very unlucky with. I have never encountered anything like this on the PC version.

Please let me know what’s going on here! Thanks.
