Lua Ladder bug when any item is below

[ondrake]

Hello! I'm having a strange problem and i hope you guys can help me.

I found out that the ladders cannot be used when there's any item below them or fire.
using OThire GitHub - TwistedScorpio/OTHire: OpenTibia Server for Tibia 7.72 ultimate version no modified, linux debian 7 and 8
I already reported on github but the creators did not respond.
I already checked the items.otb with the item editor and object build this normal.

function onUse(cid, item, frompos, item2, topos)
newPos = {x = frompos.x, y = frompos.y, z = frompos.z}
if (isInArray(LADDER, item.itemid) ) then
newPos.y = newPos.y + 1
newPos.z = newPos.z - 1
doTeleportThing(cid, newPos)
else
newPos.z = newPos.z + 1
doTeleportThing(cid, newPos)
end
return true
end

No one to help, dammit.

I found the error, in the parcel trap that I had added
game.cpp

//the first down item is usually the right item unless there is topOrder items with scripts
                Item* downItem = tile->getTopDownItem();

                //check items with topOrder 2 (ladders, signs, splashes)
                Item* topOrderItem =  tile->getItemByTopOrder(2);
                if(topOrderItem && g_actions->hasAction(topOrderItem) ){
                    const ItemType& it = Item::items[topOrderItem->getID()];
                    //if the top order item has a height or allows pickupable items we use the first down item instead
                    if(!(downItem && (it.hasHeight || it.allowPickupable))){
                        thing = topOrderItem;
                    }
                }

                if(thing == NULL){
                    //first down item
                    thing = downItem;
                }

                if(thing == NULL){
                    //then items with topOrder 3 (doors etc)
                    thing = tile->getTopTopItem();
                }

                if(thing == NULL){
                    //and finally the ground
                    thing = tile->ground;
                }
            }
            else{
                thing = tile->__getThing(index);
            }
