+Game Frozen or Stuck?
+=====================
+
+Infinite Loop in NetscriptJS
+----------------------------
+
+If your game is frozen or stuck in any way, then the most likely culprit is an
+infinitely running loop in :ref:`netscriptjs`. To get past the freezing, run the game with
+`?noScripts` in the URL:
+
+`https://danielyxie.github.io/bitburner/?noScripts <https://danielyxie.github.io/bitburner/?noScripts>`_
+
+Then, to fix your script, make sure you have a sleep or any other timed function like `hack()` or
+`grow()` in any infinite loops::
+
+    while(true) {
+        // This is an infinite loop that does something
+        ...
+        await ns.sleep(1000); // Add a 1s sleep to prevent freezing
+    }
+
+Bug
+---
+
+Otherwise, the game is probably frozen/stuck due to a bug. To report a bug, follow
+the guidelines `here <https://github.com/danielyxie/bitburner/blob/master/CONTRIBUTING.md#reporting-bugs>`_.
