Pizza stays small when dragging to workstation

[cbujara]

In the course of testing this morning, we ran into a few instances where the pizza remained small when dragging it to the workstation, and no ingredients could be added to it. Dragging down a different pizza clears the image of the small pizza, as does switching workstations. We think it may be related to two chefs grabbing the same pizza simultaneously, but have been unable to reproduce consistently. Possibly latency-related, occurring only when work queue updates don't propagate quickly enough?

I've spent some time trying to reproduce this bug from the bocoup-2015 branch
(that's without gh-158 applied), but I've had no luck so far. In the interest
of making headway on the project's open issues, I'm going to shelve this for
the afternoon and focus elsewhere. I'll spend some more time investigating
tomorrow!

It's tricky because it happened a few times to different chefs on different machines, but we weren't able to figure out the correct combination of circumstances to reproduce it. I've never run across it when testing on my own, so I suspect it's related to a concurrent action that I'm unable to reproduce with two hands and one mouse.

I've also been testing with two physical machines. You should see the set up--I have an ethernet cable stretched across the room at knee height. @leobalter labeled it as a "trap", but it's really doing a good job containing @Wilto to his desk.

It's a trap! When you add a robot to the mix to simulate another player, I will be super-impressed.

If it would help at all, we could set up a time tomorrow to test the interactive with some other humans. That would also provide a greater likelihood of latency issues that could be a factor. We could all record our screens and try to capture the elusive moment, which of course won't happen because we're looking for it.
