I don't have a crash report to provide but the wye tracks on this mod aren't showing up. I tried JEI and crafting but still nothing. I am using the latest (I think) Railcraft from curseforge and all of my modules are enabled in both my Railcraft modules.cfg and ingame interface on modules.

Mods:

Basically a duplicate of #1364. Whack a piece of track with a spike maul

Look at your advancements bro. The advancement with the turnout track icon tells you how to make a wye track
