Minecraft ftb stuck on downloading pack data

There is one thing I found somewhat annoying, though. Upon launching a Forge pack, there is only one progress bar, which seems to progress rather smoothly right up until the end of it, where it looks to freeze. The game is not frozen, however, and the memory usage still fluctuates as normal. It is still responding and operating normally, it just looks to be frozen. It sits like this for some time. Being accustomed to the 3 rows of these progress bars and having the little hammer and anvil in the bottom right doing it's animation to reassure you the program is not frozen , I find this change a bit unsettling.

It's nothing too major though. However, upon staring at this screen for a bit, I did notice the bottom left corner, which at this stage reads "Freezing Data". Freezing data while the program appears to be frozen? Ironic, at least. So, the main purpose of this post: What does this "Freezing Data" actually mean? What is going on at this stage of loading?

When you then disconnect, Forge has to revert to the previous stage the one you would get immediately after game startup. To do this, Forge copies the registries once after startup, this is most of the work in "freezing data".

Then some registries have other data dependent on them, for example block states need to have their IDs recomputed based on the block IDs. This also happens here. You can post now and register later.

Delete your old launcher, and download a new one from the website. For another issue a friend of mine just had where clicking the launcher does nothing entirely, on Windows open a command prompt, and type: java -version If it returns your java version, and Build info, you'll have to re-install the FTB client.

If it returns an error, you will need to re-install java. The 64 Bit java client can only be downloaded as an "Offline Installer" not the standard installer. Hope this helps! Sundaysmiles Guest. Just tried to open the launcher via my desktop icon and it stops loading after recording the above errors. Global Moderator. Trusted User.
