i use that mod above and it changes DLC1HunterHQWorld "Dayspring Canyon" [WRLD:03001DB8]in the Location NAM0 and NAM9 a great deal. they should be -5 n 5. they are -27 n 53. it also changes CELL X and Y Offset. in these threads they state how changing the NAM can be bad.
i've corrected a few other areas where mods had changed them, and all has been fine. no areas out of bounds or crashes ect. but i'm wary of correcting this since that mod places quite a few things up a path to Dawnguard Daysprings. i'm guessing that's why the larger NAM. so i'm wary to change them back to original. will that make objects disappear or the like? should i chnage the NAMs back to original
