Try deleting your spawnpoints.lua file, remaking it in WorldEd and saving it again.
Here is an example of Bedford Falls spawnpoints.lua file:
function SpawnPoints()
return {
constructionworker = {
{ worldX = 46, worldY = 34, posX = 40, posY = 152, posZ = 0 }
},
fireofficer = {
{ worldX = 46, worldY = 34, posX = 40, posY = 152, posZ = 0 }
},
parkranger = {
{ worldX = 46, worldY = 34, posX = 40, posY = 152, posZ = 0 }
},
policeofficer = {
{ worldX = 46, worldY = 34, posX = 40, posY = 152, posZ = 0 }
},
securityguard = {
{ worldX = 46, worldY = 34, posX = 40, posY = 152, posZ = 0 }
},
unemployed = {
{ worldX = 46, worldY = 34, posX = 40, posY = 152, posZ = 0 }
}
}
end
