Awesome line of mods, love it for our modpack and server.

We are getting this error in SP tests.
Crash log here.

When using vanilla crafting table.
It seems to happen only when we have Crafting Tweaks installed as well.

Forge-28.0.81.jar
FastFurnace-1.14.4-2.0.0.jar
CraftingTweaks_1.14.4-10.1.3.jar (in case it helps)

Hope it helps to get full compatibility. Thanks.

You're using an outdated version of FB, which references methods that have since been removed from placebo. All you should need to do is update.

I posted the wrong file (FastFurnace-1.14.4-2.0.0.jar).
It's FastWorkbench-1.14.4-2.0.3.jar
And yes it is the not the latest.

Thank you so much for pointing it out and answering so quick.
Working perfectly fine w/latest FastWorkbench-1.14.4-2.1.0.jar

Awesome work.
