I'm back with yet another issue. Minecraft produces a NullPointerException while handling the Thaumcraft bit of your mod. Here's the relevant bits from the log - excluding the list that shows the Thaumcraft part of your mod errored during pre-init.

This time, I have Thaumcraft installed but not ProjectE, though (the lack of) ProjectE doesn't seem to be the cause here.

Well, everything (including Thaumcraft and regular Reforged) works fine if I remove Integration. Where else could the problem lie?

I have no idea, what could be the issue there... For me it works perfectly though o_O
But it doesn't even look like an error of my mod (seems like the API of Thaumcraft would be broken a little bit).

I have a suspicion, but cannot test it without having a reforged-integration workplace set up.
The fact that the error only occurs in the musket+knife recipe (line 93) and the NullPointerException might mean that there is a problem with setting the values for knife or musket before.
Better check what their values are before line 93.
But maybe make sure you are using the same code first.

I really can't reproduce the error and have no idea what is the problem, I will look at this again, when I am finished with the crossbow.

Could you please send me the whole log and the crash report (please separately out from the crash-reports-folder)? That could help me further.
P.S.: Which version of Reforged, which version of Reforged Integration, which version of Thaumcraft and which version of Forge is installed? You need at least Reforged 0.7-pre1 to run the Reforged Integration 0.2-builds...

At my client, it generates logs since the launcher closes... This is crazy o_O

I'm not sure which log you're after (and where I could find it), but here's a pastebin with the full crash report.

I did double-check which Reforged version I was using and it was indeed 0.7-pre1. You'll be able to see it in the crash log I pastebinned as well.

in your minecraft-folder, there should be a directory, called "logs". There is a file fml-client-latest.log. I need that file (if you ran minecraft with our mod)

There's no log file regarding this error. I'm assuming this is because the crash happens during the pre-initialization phase, whereas these logs only show events after a world is loaded.

Wait, did you disable the musket in the config? If you did so, I know the problem (and I know how to fix it... I will even fix it, if you didn't disable it XD ). For my client it still works:

The musket was not disabled.

However, I think I found the exact place of the issue: an old config file of Reforged Integration that had the compatibility settings reversed compared to my mod loadout: Thaumcraft = false, ProjectE = true, while I didn't have Project E and did use Thaumcraft. Correcting that (Thaumcraft = true, Project E = false) solved the issue.

Is it possible to let Reforged Integration check which of the two mods are available and load content based on that?

I have already tried this, but I had the problem, that you can't change the config then yourself (as a modpack creator you may have to do this for balancing). Maybe I find a better way for this later on...

Ok, I will just remove the config in the next update... I will try to find a better way anytime later on...

I will release the new version in a few minutes
