If you would put a debug msg after the if round statement would that appear?

Can you try this?
Python: 
try:
      Entity.Destroy()
except:
      Server.Broadcast("Something is wrong with: " + str(Entity))
      return

With Entity.Destroy() commented out is it fine. With it in it will still destroy the object but just give the error. It doesn't seem to effect anything, Its just annoying.

Also doing the try: except: still gives the error

If It happens with Try, then It is not the destroy function.

I removed some unnecessary coding stuffs, and changed the structure of the code to help you understand what's continue.

Give it a try.
Python: 
def On_EntityDeployed(self, Player, Entity):
    if Entity.Name == "WoodPillar":
        #Entity locations are in float, this is just a case stuff.
        height = round(float(DataStore.Get("BuildingRestriction", "Max Height")), 0)
        for foundation in Entity.GetLinkedStructs():
            if foundation.Name != "WoodFoundation":
                continue
            if height < Entity.Y - foundation.Y:
                try:
                    Entity.Destroy()
                except:
                    Server.Broadcast("Failed to destroy the entity.")
                Player.Inventory.AddItem("Wood Pillar")
                Player.InventoryNotice("1 x Wood Pillar")
                Player.Message("You are not allowed to build more than [ " + str(round(DataStore.Get("BuildingRestriction", "Max Height"), 0) / 4) + " ] pillars high")
                break
    elif Entity.Name == "WoodFoundation":
        count = 0
        max = int(DataStore.Get("BuildingRestriction", "Max Foundations"))
        for foundation in Entity.GetLinkedStructs():
            if foundation.Name != "WoodFoundation":
                continue
            count += 1
            if count == max:
                try:
                    Entity.Destroy()
                except:
                    Server.Broadcast("Failed to destroy the entity.")
                Player.Inventory.AddItem("Wood Foundation")
                Player.InventoryNotice("1 x Wood Foundation")
                Player.Message("You are not allowed to place more than [ " + str(DataStore.Get("BuildingRestriction", "Max Foundations")) + " ] foundations")

If you see it on the console, the rest of it is in the rust server log in rust_server_Data, not the Fougerite logs in the plugin area.
