I came across a scenario whereby my tradepile was maxxed out, but none of the players bought were being listed. As a result, internal server (500) started cropping up after leaving it running overnight. Information:

Autobuyer version: 0.5.0

No players in tradepile initially. I added 3 players to autobuy (Wilshere, Son, N'jie).

Set the settings to the following:

RPM: 20
Min Credits: 1000
Max Players: 70

I had check the auto pricing to, 75; 95; 100.

When I looked in the morning, I had bought 70 players, but none of them had been listed. Any ideas?
