Moarsigns 6.0.0.11
Forge 2838

Issue:
Even after disabling replace recipes in the config the mod is still replacing signs with its own. This is creating an issue where all recipes needing the vanilla sign are impossible, and mods/npc's relying on vanilla signs are unable to function.

Proposed solution:
-A setting whereby using oak produces the stock vanilla sign, and using anything else makes the respective signs from this mod, as applicable.

Also having this issue with floo signs

I like the proposed solution:

specific integration with random things would also do, but it wouldn't solve this issue for other mods

For anyone who might want it, I made a CraftTweaker script that adds a recipe to change wooden MoarSigns into vanilla signs.
You can find it here.

I am having this same issue. I am testing it in an environment with only RandomThings, MoarSigns, and JEI.

Versions:

• MoarSigns-1.12.2-6.0.0.11
• forge-1.12.2-14.23.5.2838-universal

Here is my config:

# Configuration file

general {
    # Replaces the vanilla sign in recipes with signs from MoarSigns
    B:replaceRecipes=false
}

Because of this issue, my players cannot craft Floo Signs, because they can only be crafted with the vanilla sign. I also tried to make all MoarSigns' sings compatible by adding them to an ore dictionary entry and requiring that in the recipe, which didn't work - but that's probably best put in another ticket.
