The idaho-florida-speaker crash commonly known as the “Alta Street Crash” and the “Metro Underground Crash” is caused by the loading of the following IPL "v_tunnel_hole_swap" when loaded together with “v_tunnel_hole”.
The crash can be reproduced on an empty server, by loading the following two IPL’s together and driving under the Alta Street Construction Site on the metro line.
Loading either by itself does not cause any crashes, only when both at loaded in.
The following code was added to produce the crash:
Citizen.CreateThread(function()
RequestIpl("v_tunnel_hole")
RequestIpl("v_tunnel_hole_swap")
end)
