[2.0.66] Error while running event level::on_nth_tick(1)

[zsoltvaradi]

On the menu screen I am consistently getting the following issue when a Nauvis scenario should show.
build 83840 expansion, win64

The scenario level caused a non-recoverable error.
Please report this error to the scenario author.

Thanks for the report. Log file indicates you have mods enabled. In general if mods are involved then we no longer care about menu simulations crashing because they are heavily scripted and if mods change essential entities that are involved in the simulation, then it may start behaving incorrectly. In this specific case i observed the issue to be nauvis_tank_building simulation that was failing because a tank was driven into factorio logo entity causing tank to be destroyed which later caused a script crash due to tank no longer being present. For 2.0.67 i made a miniscule change to make this specific simulation at least not crash if tank is destroyed which will fix the crash, but that still keeps the menu simulation not play the way it was supposed to.
