Oasis Desert Crashes Game.

I have the same problem

I also have this problem. Of note, it didn't happen to me immediately at the start of summer, because it was still raining and wet. But once the rain dried up and the sandstorm started, I also can no longer travel to the oasis desert without the game crashing. 

I'm playing as Wanda, and I have a Backtrek watch set up at the oasis itself, and the crash occurs both when walking into the oasis desert and when teleporting there. It certainly seems like from what I see that the sandstorm is causing the glitch.

I'll do some further testing to see if other typical summer things happen, namely Antlion making sinkholes. And I'll play through summer into autumn later today to see if it truly is exclusive to the sandstorm.

Yes it's because of the sandstorm

Same here actually literally unable to redo celestial champion in other world because of this
