Graphics Settings

Even though TerraTech World's minimum spec for graphics cards is 6GB, the game now detects whether the GPU has less than 6GB and switches to low VRAM mode where necessary.
FSR anti-aliasing has been disabled as it's causing extreme ghosting.

Bug Fixes

Blocks with a zero count in storage are no longer shown.
Blocks purchased from a trader in Classic mode now correctly go to your storage instead of your cargo.
Fixed bug causing duplicates of recipes to purchase appearing in the list.
Favourite button functionality now works properly in Creative Mode.
Fixed crash that may occur when loading a complex Tech snapshot then trying to load a new snapshot in its place.

Until next time, Prospectors!
