Random `.startsWith is not a function` bug
Randomly will begin to receive the following error stack, after a while it sometimes just stops.
TypeError: role.startsWith is not a function
at Object.run (SpawnManager:75:22)

When it's happening, right before that error do a `console.log(JSON.stringify(role))` and see what's in role.
sparr: role is creep.memory.role, inside a loop of Game.creeps.
All of my creeps have a role, and it makes no sense for the error to be intermittent.
That's what it's supposed to be. Log it to find out what it actually is.
I failed to elucidate properly.
This code has run for weeks properly on the live world.
There is no rhyme or reason for it to intermittently fail on a private server, unless something wonky is going on in the server.
Yes, and the first step to diagnosing what is going wrong in the private server is to see what role contains when the error happens. I didn't say it was a problem with your code, just that modifying your code is the quickest way to get insight into the problem.
