TFS 1.X+ Nekiro TFS 1.5 Dawnport Debug Crash Client by Items

Mister Budex · Jul 8, 2022

I've found a bug which is probably related to items.otb as something seems wrong, by some investigations there are over 80 invalid items in items.otb which cause this crash, so on a normal 8.60 regular client client just debugs whoever appears on screen or floors +1/2 , -1/2. One of these items is POT. so here i can show you a video
OTCV8 - POT

Regular 8.6 - POT ( After creating item, just crash)

Here is log packet from terminal of otcv8

Code:

6a 5f 00 74 00 07 03 89 0d 83
5f 00 74 00 07 0f

6a - add tile item packet
5f 00 74 00 07 - position
03 - stack position
89 0d 83 - Item

from your Nekiro 8.6 (I get it on Discord from Budex):

Code:

void NetworkMessage::addItem(const Item* item)
{
   const ItemType& it = Item::items[item->getID()];

   add<uint16_t>(it.clientId);

   if (it.stackable) {
      addByte(std::min<uint16_t>(0xFF, item->getItemCount()));
   } else if (it.isSplash()) {
      addByte(fluidMap[item->getFluidType() & 7]);
   }
}

89 0d is item ID, converted to decimal (137 + 13 * 256) it's 3465, it should be pot ID in Tibia.dat
83 - client reads this value as fluid type, which mean's that client expects - based on Tibia.dat information - pot to be able to contain some fluid, but server did not send this value as fluid, it's number of next packet (animated effect on tile on which you created pot as GM)

Here is fix from official Nekiro that your engine is missing:
