So this is the main crash.
Comparison method violates its general contract!

Caused most likely by this line:
at minecrafttransportsimulator.entities.components.AEntityD_Definable.update(AEntityD_Definable.java:400)

The code it points to is here:

MinecraftTransportSimulator/mccore/src/main/java/minecrafttransportsimulator/entities/components/AEntityD_Definable.java

Line 400 in 0117ecf

groundersOnRadar.sort(entityComparator);

And the compare function it runs is here:

MinecraftTransportSimulator/mccore/src/main/java/minecrafttransportsimulator/entities/components/AEntityD_Definable.java

Line 165 in 0117ecf

private final Comparator<AEntityB_Existing> entityComparator = new Comparator<AEntityB_Existing>() {

That all being said, what's more than likely happening is the compare function is trying to find the closest vehicle tracking a radar thing, but somehow the vehicle gets duplicated on devmode and there are two so it can't find the closest and crashes. This is more than likely due to the duplication scout glitch Mulle posted long ago and this will go away when that one does.

Mayhaps @SnailPerson can ask AI why vehicle would possibly duplicate on devmode...
