Traders don't appear in game

[mpatsift]

In the fourth game in this tournament:

pal-tournament-ph3-shared-3-1-2-M-2023-03-09-131203-openmind0_pal-tournament.log.gz

The two traders never appear, causing our agent to report novelty and fail to win the game.

Don't know if this is same as now-closed #57

We run this tournament regularly, and I haven't seen this particular failure recently.

Seen again on 18Apr23. Let me know if you want logs.

FYI our agent should report a novelty "Found 0 traders: Expected 2" when this occurs.
