Lately, I've been having a great time on the Ultimate Pack. I've got a fairly stable geothermal/Nether power source, industrial machines, nano armor, farms are being set up, a good amount of rare materials, et cetera, but more recently, weird things have started happening.
What I'm talking about is that every time I log in, all of my achievements and statistics have been reset, along with my settings (video, audio, etc), which reset to values I set a while back and are kind of annoying (muted sound is nice and all, but not getting blown up is even more nice, and I'd like to be able to see more than two blocks in front of my face) and throw me off a little bit. It's also disconcerting, as I'm worried that something is wrong.
I also somehow can't hear any sounds that other mobs (e.g. Twilight Forest mobs, Redcaps, Wraiths etc) make, and due to Optifine, for some reason, the debug profiler graph appears on the F3 menu no matter what I do and I can't see held items. These are probably unrelated in cause to the above, but still annoying and I'd like to know if there's a fix for these as well.
Is anyone else having similar issues? Would redownloading the mod pack help to fix one or more of these errors? Is this something which will happen every so often irregardless of what I do, making constant redownloads a reality? I'd really rather that not happen, as it's annoying especially with my not-so-fantastic Internet.
I'm really also not sure what the cause of this is. I'm fairly certain that this started happening one or two days after I had to restore my VoxelMap waypoints (about one or two weeks ago) from the recycle bin after clearing out %APPDATA%/Roaming/.minecraft/mods and deleting VoxelMap stuff by mistake, but the resets only started one or two days after this. This doesn't make sense to me as a cause of these errors, as there's not usually the sort of "delayed gratification" that would be necessary for VoxelMap to be the cause, and all I did was restore files. I also recently copied in an old save file from Beta Pack A into my ultimate pack saves folder, but I'm fairly certain that this was after the constant resets and not before.
Any help is appreciated, as is reading this and putting up with my rambly and annoying nature
