Automatically resetting game stalls after several iterations

[pgalatic]

Expected: The game always resets when the "play continuous" flag on Toolbox is checked
Actual: In a situation where there are no players, performs as expected at first, but after a while the City spawn rings' hover animation starts improperly, and the the PlayerAI_Basics spawn units endlessly without sending them anywhere.

Steps to reproduce: Start a game and let it run for about seven iterations.

This is a low priority that may be fixed inadvertently as development progresses, and it does not hinder normal gameplay. I suspect that certain coroutines are not starting as smoothly as I expected.
