Was on Dand.
Went to sanctum from menu.
Crashed to desktop (could not send a report).
Since you need to know which planet your creative planet is tethered to for portal/travel purposes, it would be great if that info was displayed in the GUI someplace.
I was not warping at any point when I crashed. I was at my base on Havran I laying out some blocks both times I crashed. I had not yet visited my creative planet, I did check the portal in sanctum to see how much time I had been given on the test planet. I had not warped anywhere yet today.
I get the same message as @majorvex when I go to the portal in sanctum and try to get to Havran and Havran I does not appear in the sky. My creative planet (Titan) does appear in the sanctum sky.
I am not sure of this is useful or not. When I look at the friends screen in test, I can see information for Peyago who I am pretty sure has not been back on test since the last release and for Stretchious who has been back on test since the last release.
