Nur bei Arcanen Rezepten. Aber wie gesagt wenn ich die überschreibe und Refreshe sind die weg. Brauche den Remove Code nicht. Azanor schrieb dazu folgendes:

https://github.com/Azanor/thaumcraft/issues/1539
https://github.com/Azanor/thaumcraft/issues/1532

Only with Arcane Recipes. But if i override the recipes (with the same recipes) i not need the remove code. Azanor writing something when i posting this error:

Wenn es nur so geht wurschtel ich mich da durch. Ist zwar nicht die beste Lösung aber wenigstens eine.

It would help if you supply the script.

https://github.com/Dream-Master/DreamCraft/blob/master/scripts/Thaumcraft.zs

Die Zeil wird nicht benötigt
import mods.thaumcraft.Arcane;

Bei Version 6 konnte ich noch Arcane Scripts removen jetzt wirft der nur noch Fehler raus.

Super das ihr jetzt Forestry unterstützt.

Hab ne Lösung gefunden. Ich überschreibe das Rezept mit einen Nonsens Rezept. (6 Copper Nuggets geben ein Copper nugget) und dann geht es. Komisch. Wird zeit das ich mich noch mehr in java reinknie um Probleme besser zu lösen. Ich lass es offen vielleicht gibt es ja noch einen bessere Lösung als diesen Hack.

Found a solution. I override the recipe with a nonsense recipe (6 copper nuggets to 1 copper nugget) which works. Weird. I should spend some time for Java so that I can solve problems more easily. I leave it open, maybe there will be a better solution than this workaround.

Könntest du raussuchen welches Rezept-Removal genau den Error verursacht? Das würde es leichter machen.

Could you track down which recipe removal causes the error? That would make it more easy.

English or I cant help...

Yes sure my fault.

I try to explain my problem.
If you have a Arcane Table Recipe (Copper Wand Caps) you cant delete it (mods.thaumcraft.Arcane.removeRecipe) it throw out the code in my first post. Now i try to override the Recipe with a new one and refreshing the research. Now you have both Recipe (the old one and the new one) after i override the old recipes with the same ingredient (copper nugets )like the orginal and link it to a item like dirt or something else (using 1000 vis each aspeck that no one use this recipe) it worked showing my new recipe from the Copper Wand Cap (and the fake Recipe with the expensive Dirt) After this i can add the line "mods.thaumcraft.Arcane.removeRecipe...." and there is no error any more.
i see you didnt change any thing in the code only rename it to modtweaker 2. So i dont know what happend.

I asking Azanor some weeks ago about this thing and he give me this answer:

Bdw. I don't want to complain about anything you continue this mod and make a good jobs. Thanks

I shall test when I get back home. Thanks for the report.

As Azanor already said - this isn't possible for some items, including the wand cap and the wands. Sorry!

Ok than i create a fake item in my core mod and override all recipes. Ok many things to do.
Thanks for help.

Maybe TPPITweaks is able to do it? Calling @tterrag1098

But it isnt right ?

I was saying no, I don't have a way around this.

Thanks.

Another Question. (i wrote in Minetweaker git too) is it possible to update Gt to Version 5 /6 and add Fluid support because Stan not working on the mod since a while.

Heh, nope

?

@jaredlll08
I see you working on the Arcane Handlers. That mean this bug get to be fixed ?

For some items yes, for some items no.
