I was in twilight forest running around while it was raining, i'm using age of fate 1.4.6 (tried it using 1.4.3 as well, I've got 12gb of memory allocated to it (out of 32)

Twilightforest currently have issues with Manesium mode. It's a rendering issue between twilight dark oak and magnesium.
In the newest update of Age of Fate I've temporarily disabled the portal to Twilight Forest dimension.
