Does this happen without any other mods installed? And is this reproducible every time?

Yes even without any other mods installed, and every time we click on the trade button.

You are not using the latest mod version, does it happen with the latest version?

Yes, we tried both

Can you send me the logs of the latest version without any other mods?
