I already informed Boni and Darknight of the issue and DK is working on his mod. Just wanted to let you know that sojourner's sash does the same thing as the boots of the traveler (TiC) with TYNKYN installed.

NOTE: Traveler's Boots (TC4) so work.

So what is the problem?

What IS the issue though? Does it break step assist when you equip it? Does it break it when you remove it? What happens?

Sorry. You don't step up at all. Step assist works for TC4 but not for Botania and TiC.
Again, sorry.

Mod interaction issue, but I don't know on who's end. So I am informing all authors affected.
I believe that it has something to do with TYNKYN's "step-up" potion effect, but I'm not a coder and can't check into it.

I'm ruling this out as something on their end. If the author comes back to me you can point and laugh.

Thanks. New update, so hopefully it's fixed.
