TFS 1.X+ [Bug Client] if stackpos greater than 10 then BUG end

[Error 502]

discovered a bug in nekiro 8.0

if 10 people stack in a specific position (tested in normal_zone)
the client presents the following bug


For some reason if there are many people stack in a sqm gives debug
example:
-at the end of an event of 10 people and the end of the event makes teleport to the same sqm at 10 people gives debug

+10 people stack on a ladder

Comment:

try a patch solution that at the end of the event they are teleported to random position
But there are other ways to cause debug as stack intentionally

I'd try with that:
ProtocolGame::GetTileDescription(const Tile* tile, NetworkMessage& msg)

C++ - +9 players in some stack debug

In my server when the players stack in the same sqm when the number 10 go on in stepin the last one takes debug. When someone in stack of +9 players logout all clientes in stack takes debug too. Can someone explain to me why this happens and how I can avoid? Thanks guys. I do a video explain...
