All workers stop moving

[parsehex]

One of the most bizarre bugs so far: Occasionally, with no noticed pattern as of yet, all workers on the map stop moving with some exceptions.

In the above game, the Planter was still able to move, but was obviously stuck between trees. This was the only planter at the time but not the first of the game (so this one was most likely recycled). The Choppers and Collectors were all fired during this bug and re-hired (the ones in the picture are the re-hired ones), yielding no results (none of them moved).

Observations from various plays:

• When the bug starts, you seem to be able to "jump-start" the workers by either collecting an item or chopping a tree down.
• There is not a high number of Web Workers active (not the max or anything; above game had 4 WW active).
• From some pocking and proding in Chrome DevTools, it appears that the pathfinding WWs are running and (presumedly) returning path data.
• Over time, chopping down trees and collecting items no longer jump-starts the workers.
• Hiring and firing doesn't jump-start, at least later in the bug when collecting/chopping stops jump-starting.
• Pausing all active WWs, causing new ones to spin up doesn't jump-start either.
• As noted above, the bug doesn't always affect all workers.
• (Noticed at least twice:) When the bug first starts, all frozen workers are facing tiles that they cannot work on (i.e. no Choppers facing trees, no Collectors facing items that can be picked up). As far as the picture, I believe the Chopper facing a tree was from hiring placing them there.

Current guess is the worker-pool.

Had a playthrough where this bug did not happen:

• 9 total workers (6 Choppers, 3 Collectors)
• This is after adding worker idling and smarter Collector
• By the end, there were 5 Web Workers spun up (only 4 moments before though)
