IronBackpacks fails to load on recent Forge 1.8.8 builds. I guess this is due to the new registry fixes (for example MinecraftForge/MinecraftForge@97ef6a5).

Relevant line from the log:

java.lang.ClassCastException: java.lang.String cannot be cast to net.minecraft.util.ResourceLocation

Crashlog

IronBackpacks: 1.8-1.0.6
Forge: 11.15.0.1608-1.8.8

Hrm... This might remove compatibility with 1.8... I guess that's fine?

Do whatever you think is best, I'm not sure.

I'm testing a fix that might allow both

Thanks for the quick fix! It starts up now without crashing.

One thing I have noticed though from quickly trying it out in creative, is that I'm not able to equip a backpack with 'B' as is stated in the MCF post (I couldn't find any other shortcut that would equip it for that matter...).

Yes, that is because it isn't implemented in the 1.8 version. I only have time to work on 1 version (1.7) and TehNut is busy as well, so the 1.8 version will be less feature rich than the 1.7 one will. I should make that more clear in the MCF posting though.

No pressure. I can open a separate issue, if you think it's appropriate.

The current 1.8.8 modding situation is pretty dire anyways...

No, I'm working on it right now. Just have other projects that need my attention a bit more than that.

Not really...
