Hi! I forwarded to line-pack maker (Ptterz). We will react! Thank you!
Last night I reinstalled all new Omsi 2 & Bus Company Simulator and was surprised it worked. It seems that the map: Ahlheim-Laurenzbach Updated Liniepack 2021 is already pre-installed on your BCS server. Only without separate Omninavigation installation, because Bus Company Simulator program includes Omninavigation. I didn't poke anything, it automatically detected it, that's all. And it was correct to draw the red lines.
