Hey there. I know this mod is WIP, so here's a crash report. Occurs without the extra mods. Just Traffico and FP2 installed.
I am running a snapshot I got from the mod creator shortly before he abandoned the mod, so I'll include it I guess.

sorry, but i'm not dealing with mod compatibility at this point (since the mod hardly works with vanilla). i'll close this issue for now and re-open it if needed once it's more stable.
