[LE] Creation kit - Warning - mesh/texture problem

[EternalJudgment]

Hi everyone, rescently i've been working on a mod, making a new town in Hafingar hold! Anyhow at some point, one of the "walkwayCwallsnow01" had 90% disapear in kit & seems to spam them warnings;



I've reinstaled skyrim se , the creation kit , look over in the files and everything seems to be good but not in the kit/ ingame since!
Any help would be gladly apreciated!
