i been trying to play allthemods and it won't work, i have tried both server and single on single i create world it says building world but never builds i let it try for 3 hours once and nothing and when i try to log into a server it says loging in but then goes back to main menu

We'll need to see logs to get more details but also try fully re-downloading the pack as a fresh profile. Check to make sure you're allocating at least 4gb of RAM as well.

Can you give details of your computer spcs (CPU/RAM/OS) and find the latest.log from the modpack directory and upload it here for us to take a look at

there is no crash report thats the problem because it doesn't crash it just won't let me load into a world

latest.log
crash-2017-12-27_22.49.04-client.txt
and that crash appears sometimes on step 3/7

First of all, 6gb total RAM is going to make it difficult. Not impossible but difficult to load a large pack like ATM3, itself needing 4-6gb of RAM to run smooth.

That being said, I've seen this error more and more comingup lately:

net.minecraftforge.fml.common.LoaderExceptionModCrash: Caught exception from Just Enough Dimensions (justenoughdimensions)

Caused by: java.lang.IllegalArgumentException: Invalid dimension id 6

And I've spoken with the mod dev of JED and the cause is shrouded in some mystery of vanilla issues or something. I have seen this "fixed" by simply re-downloading the modpack as a fresh instance and trying again. If you haven't tried that yet, please do and let me know.

yes i tried i even deleted the mod and downloaded from curse and would not load in yet if i remove and load the pack i can log in

Here is my crashlog:

https://pastebin.com/iwTbNbXm

I have updated JustEnoughDimensions to the latest version and now I can create a world without a problem!

yes i manually updated jed but i havea question why on part 3-7 1/1loading resouce modle textureminimap and up load that has w/e/27860 that it literally takes an hour to load all 27860 of them. i get about 2-4 done every 2 or 3 seconds

i updated to the version released yesterday and it works thankyou for your time

@patyak do you mean you manually updated JED to the new version from curse?

@TwoWorlds can you try manually updating JustEnoughDimensions to the latest version (the alpha from Dec 28 or later) and see if that fixes the problem for you?

@patyak that's unrelated to the dimension crash but it means that you don't have enough RAM allocated to the pack and Minecraft/Forge has to constantly fight itself for more RAM while loading. If you don't have a lot of total system RAM it can be hard finding the number that works just right overall but you probably want to shoot for at least ~4.5gb allocated. 5-6gb if you can spare it.

ok thank you very much for everything
