World Generation error

[YoanTQL]

Hey,
i'm playing with friends on a server.
it looks like we generated something causing troubles by exploring the map.
i tryed to check logs and i think it's the better-desert-Temples mod causing problem by generating something.

My ability to red logs stop here, i don't understand what exactly cause the problem and now make the server close the moment we join.
Can u help ?
