Okay, so I'm trying to install flan's mod, but every time I install forge my minecraft refuses to run, this has been going on for months to the point where I've just given up trying. Every time I copy the files from the Forge .rar to my .minecraft .rar folder, I get this error message:

 

*** MagicMinecraftLauncher 1.0.0 ***

even without deleting the META-INF folder, it does the same thing after I do delete the META-INF. Also when not using magic launcher, it just goes to the updating screen, reaches almost all the way across the loading bar, and says "Done Loading" but doesn't move any further. Help please.

If you're using Magic Launcher, why are you installing the mods manually?

There's an EAQ for a reason. Read it!

Oh, and logs OR IT DIDN'T HAPPEN!!

this is exactly what I have been doing, both manually and through magic launcher, I'm not an idiot, I've been using Flans mod since it came out, but the new versions that require forge have never worked for me. So can someone please ACTUALLY help, and not just tell me how to install something I've installed a million times without problems.

Run the batch file found in the Rules and EAQ. Then post the output here.

This is the error report from the batch file, pretty much the same thing.

    • I made a huge forge 1.7.10 mod pack but whenever I try to create a singleplayer world I get the error saying "A fatal error has occurred, this connection is terminated." Does anyone know what the issue could be?  Here is my fml-client-latest.log from when it crashes: https://paste.ubuntu.com/p/3rKSJSqnrX/ and here is the list of mods: https://imgur.com/a/AZifMbg

    • Made a modpack (Well Rounded Blockheads, in case the modlist on curseforge helps) and server to host it, worked fine until last night. The issue that pops up after some days being up/working is when you leave a world (singleplayer) or shutdown a server, the process hangs and jumps to 8.5gb ram used, eats up CPU usage (50-60% in taskman on a 3800x) and just sits there. If done on a single player world, the game doesnt fully crash, (e.g. if you alt+f4 buttons like save and quit, options stay in the window, are still clickable but they do nothing) Saving seems to still happen, as location/inventory updates if I restart server or client and play the world again.   If I start the currently afflicted server but dont login the server closes properly, its only once I log back in the problem occurs. Its a priv server and I dont have anyone else to test atm so Idk if its a prob with my player or players/area in general. Only recent changes in game are the additions of a pnuematicraft pressure chamber, an enchanting table, and bookshelves from builders crafts and additions.... I've been trying to get help on this all day, so ANY assistance goes a long way, even if its a way to debug this myself >~< Debug/Latest logs
    • Thanks warjort. I was afraid, that this is because they are entities. Now I know where to dig. But what about water, for example? I have checked via debug code, that there is no entity there (appropriate method return null). What is wrong with liquids?
