[AA] Terrain looks different in Live Mode than in Manage Worlds

I noticed that the terrain on Hothead Rock Hideaway in Wanderwood Wilds looks significantly different in Live Mode than when building from Manage Worlds.

When building from Manage Worlds the terrain looks quite normal. In live mode the grass almost has a neon green color and the contrast is quite stark.

I attached some screenshots which show the terrain in BB either from Manage Worlds or from Live Mode. The spring picture has been taken in late spring (Thursday in game). While it seems to change with the seasons a little bit it's still noticeably different.

This issue makes building really difficult. I spent literal hours obsessing over terrain paint only to notice that the lot looks totally different when actually playing.

Tested with mods removed and after a game repair, graphics settings on ultra.
