It does not seem to crash for me if I use splitString with anything other as "" first, for example: " " splitString " ";

If I use "" splitString " "; after, it will not crash. When I restart my game and execute "" splitString " "; first thing upon entering preview in the editor, it does crash.

I've attached a zip file with some log files.

Crashes for me as well.

1. Open editor, place unit down and hit preview.
2. Execute "" splitString " "
3. Game crash

Open the mission.sqm, search for player unit. There is a vehicle entry in there - change it to "turtle_f";

Example:
class Item0
{
position[]={2565.4976,0.24377738,5994.6411};
azimut=30.265884;
id=0;
side="WEST";
vehicle="Turtle_F";
player="PLAYER COMMANDER";
leader=1;
skill=0.60000002;
description="Rifleman";
};

There is a repro mission in crashlogs.zip.
