yes i agree, either that or make walls nonstackable it's kinda retarded

Exactly what I thought at first. I dunno , I heard it was this way (it stacked) on IN but as I remember 0.51a wall spell only would renew the decaying timer on remaning parts on ground/put new "parts" to the ground where previous wall decayed already, but the existing parts wouldn't stack in same tile... Although, Siren suggestion might be even better. Wall of stone beats dispell field in so many ways right now, its just impossible to reach someone who spams wall scroll over and over...
