As the title says. Specifically it crashes right when the Astral Infection biome is about to be spawned in; it does the notification sound of the meteor falling, and then when it is over the game crashes. When this happens, most likely you will reroll to the most recent save backup. Unfortunately for the case of me and my friend's world, this lead to the game loading up from when the meteor had already fallen, and in place of its biome all the blocks had been deleted. For anyone else that might experience this bug, I recommend that when you defeat WoF, take all its drops asap and then exit the game quickly before the astral biome begins to generate, then you can just re-enter. We both tried this in singeplayer worlds and it worked for both of us, even when the FPS mod was or wasn't enabled.

Here is the full crashlog:

Tip: This is likely a mod's fault. Disable mods one by one and check if the issue persists
