Logs point towards something to do with moonlight api- but i am too tired rn to remember which mod is using that. here are the logs

seems like there's a conflict with highspeed-rail, due to both mods providing the same functionality.

Thank ya! i ended up just replacing highs-peed rail with gravel carts. which at least in my case is what i wanted to begin with but it wasn't showing up in the prism search so manually downloaded... idk, I'm tired as heck and need to just sleep
