Crash only occurs when I enable MFR in my modpack.
Crash report: https://paste.ubuntu.com/24879527

EDIT: Game loads fine if you set B:MilkBucket to false, thus disabling the vanilla override.

Well, for me, after three days of trial and error, two corrupted modpacks that I built and one newly acquired aversion towards non-vanilla flavored milk, crashing on this issue and blaming mods like MFR, Sanguimancy, OpenComputers, Rustic, Optifine and others as I had successes to some degree disabling them; I found that disabling milkbuckets in the MFR config really made thé difference, and so allowed me to pretty much build the 1.10.2 pack as I saw fit. Thank you for this solution!

However, even after (presumably) careful reading this threat and some others, I was mistakenly editing the Forestry - Liquids Config concerning milk before, not MFR, as I had no clue if and where MFR would put these configs. So, for anyone else with the same issue, try changing B:milkbuckets from 'true' to 'false' in the config that you can find here:
Minecraftfolder\config\powercrystals\minefactoryreloaded\common.cfg
(This may be fully one me and my lack of understanding, yet I don't think 'powercrystals' or any subfolder at all concerning configs apparently thís important is a very convenient choise, nor do I think the forge-crashreport is helping me with this issue in pointing anywhere to look, like MFR or custom handling of milkbuckets. Perhaps this could one day be made clearer by the devs of the excellent MFR mod?).
Hope this may help someone with the same backery texture missing issue.

@skyboy the second i removed MFR this error stopped for mee so it is an incompatibility somewhere

Looks like there is an incompatibility with the milk changes from forestry, you have to disable the changes from either MFR or forestry and it will load, at least this worked in my case.

Not just forestry its something else too.

Pams harvestCraft will also cause this

something about this

I can proof @P3pp3rF1y statement as false.
The "All the Mods (1.10.2) Modpack crashes like "Age of Engineering" (modified with MFR and cofh only). It would be strange if Forestry would be a possible compat cause and on the other hand not.

Strangely enough I got my own modpack running one time. Maybe a coincidence?

Anyway if you remove Forestry (and all components for Forestry of course) it is running perfectly. I do not see any issue with Pam's Harvestcraft here cause it seem to run with it just fine.

The only cause for this issue so far I can confirm is Forestry.

Interesting that must be different settings or different version of forestry in my version of all the mods.

Could you actually share the forestry config that you have? This made me realize that we use forestry in dev environment all along and even when I updated to the latest version I still am unable to recreate this issue.

I never changed anything on the "All The Mods" pack and It is on the newest version. The version of Forestry the pack is using is 1.10.2-5.2.17.376 (the newest version). The difference must be on your side.
Here are the config(s) you were asking for.

I tested the solution of @Elit3WolfPack and disabled the option of the "MilkBucket" override from true to false:
VanillaOverride {
# If true, replaces the vanilla milk bucket so milk can be placed in the world.
B:MilkBucket=false
}
least in my privat pack it is now loading up just fine. It seem it is just that after all.

One last question, are you running into this issue on server? Because I tried redownloading latest all the mods version and only added MFR to it and it still didn't crash for me, but I am testing all of this in single player. Potentially on server the mod load order may be different and that could cause the issue you're seeing.

Additionally, I'd like to see if this version resolves the problem:
MineFactoryReloaded-[1.10.2]2.9.0B1-CUSTOM_BUILD.jar.zip

Just note this isn't a release and is just for testing this issue; I'll convert it into a proper fix if it does work.
Also, that is a jar inside a zip, to get around github not supporting uploading jars. I don't know either.

So far as we can determine isn't not MFR causing this crash; try disabling any other mods that alter the milk bucket to narrow down which one's interacting?

btw tried adding MFR to All the mods modpack and it worked correctly so you can likely rule out all the mods that are in that modpack as well as yours

@P3pp3rF1y singleplayer. MultiMC as well the normal Minecraft launcher. Java version is the newest. All in optimal conditions. And the issue persists.

@skyboy I tried your version and it loaded up. The world I tested it on works, too. This seem to fix it.
I have to notice: The world/pack I tested this on has no Pam's Harvestcraft. I might do testing this later.
