Duplicate Roles Happening

[mkaulfers]

Scientists, Anchors, Fast Fillers periodically duplicate themselves with no intervention/code-pushes. I'm assuming this is a possibility with any of the roles based on that it happens to 3 out of 5

Fast Fillers - When they duplicate there is a possibility that it will jam the spawn locations such that no other creep can spawn.

Anything can technically respawn prematurely. Here's the situation:

The schedule attempts to prespawn something, but doesn't find adequate space to accurately prespawn. It falls back to finding the first open space that it can spawn, and puts the spawn order there. This is creating the premature spawns that you see there.

The fixes for this are as follows:

• Have the scheduler attempt to put each "failed-to-prespawn" spawn orders in each available spawn before going to the fallback method.
• Adjust the fallback method to instead find the open space nearest to the correct prespawn tick.
• If found open space is too far advanced, modify to no prespawn spawning for that spawn order? May have negative side effects.

Any way, this is handled by #189. Closing given.
