Very odd lighting bug

[richm0nkey]

The boxlight should max be 100x100 or it these bugs will come and haunt you.

So does the max size of 100 apply to spotlights as well. because the error seems to come from the spotlight too. Fixing the boxlight made it A LOT better though . If this also applies to the spot lights is there a tutorial on how to light up night landscapes somewhere i'm not aware about? Removing the spotlight makes the terrain look kinda plain and reducing the size won't cover the terrain to make a more realistic moonlight lighting.
