Collectible Card Game Headquarters

I keep having games error out with the same (or similar) error. I have the most up-to-date version.

Any ideas?

With the next restart the servers update to 1.4.4v7 and this problem is solved.
There was a last part of server code where the 51 as default image id was returned causing this problem.
