trold has had this mod going and being updated for about 10 months now. His 0.15 update of the mod came out on the same day as this. I think you were a bit trigger-happy with getting mods updated for 0.15 and didn't notice he'd already got on it.

Nope. He's just reusing the graphics for this mod, which is why the Bottleneck mod is a dependency of Bottleneck Logistics. Nexela wrote significant parts of the optimizations for the Bottleneck mod, and in such a way that the graphics resources can be shared in memory.

This mod is an addon for Bottleneck and came out the same day as Bottleneck because I had it ready to go waiting for Bottleneck to update since Bottleneck is required for it to work.
