Crashing with “Accessing LegacyRandomSource from multiple threads”? This mod helps you find what’s causing it. When mods access the world random from the wrong thread, this detector flags it with debug info pointing to the culprit. Keep in mind: this finds the problem, it doesn’t fix it. If you’re already running C2ME, you won’t need this.
What This Mod Does
The Unsafe World Random Access Detector watches for off-thread world random access. When something tries to use LegacyRandomSource from the wrong thread, it logs debug messages. Those messages tell you which mod is the problem, so you can report it, disable it, or find a fix.
