Hm. Yet another problem with removal of verbs.
Remove_Build_Verb(mob/M in world)
set category = "Owner"
set desc = "Remove a player's build verbs."
if(alert("Are you sure?","Remove build verbs","Yes","No") == "Yes")
world << "[src] has removed [M]'s build verbs."
M.verbs -= typesof(/mob/Build/verb)
The mob's building verbs are defined under the path mob/Build/verb, but like the last time It's probably some dinky little error I don't see.
