Right, I can see why that would be happening :-). Timestamps are second-based, so if you compress tilesets containing the same layer within the same second they will be named the same (and one of them will be overwritten).

I will change the zip file naming code to really use LAYERNAME_Z_X_Y.zip which is easier (we could add the client_uuid but hey it's a feature if several clients render the same tileset that the latest would win).

Thanks for notifying.
