Thank guys,

Actually yes, I'm using Pirate Myke's terrain! lol
I will try deleting the superpalette.ter and fingers crossed.
Quote: "What are your system specs and operating system."
Not the greatest system in the world, but I've been running GG since launch with no issues, and all drivers are up to date
Update: Deleting superpalette.ter and allow it to build again has not fixed it. Changing the terrain and doing the same with the superpalette.ter on the default terrains with no joy
. I Will now try a fresh install to see what happens and will post another update.
Update2: No resolution after a fresh install of GG so I suspect the map file is corrupt somehow. Still workable but painful.
Thanks for all your help anyways, I will struggle on.
