Ok so the Elm Creek Edit By Stevie V1.0.0.3 has just been updated with the fix for the Foliage Draw Distance where if it’s set above 160% will crash the map on loading at around 21 to 23% on very high custom settings. The map file size has also been reduced.
This is now V1.0.0.4. Not tested with old games saves.
Download links remain the same here on my page but here’s one to save you looking.
