Emulator

Game Name?
Super Mario Galaxy 2

Game ID?
SB4E01

What's the problem? Describe what went wrong in few words.
Starship Mario suddenly disappears when loading a file.

What did you expect to happen instead?
It to not disappear and play normally like in the real game

What steps will reproduce the problem?
If you load SMG2 as a dumped filesystem (with paths set up for the Apploader and DVD Root) and then press the home button and go back to the home menu, it will read it as Japanese for whatever reason (I've tested with 2 different NAND dumps from my NTSC Wii so it isn't that), and then shortly thereafter pop up with "Can't read from DVD_Plugin - DVD-Interface: Fatal Error". Press the stop button to stop emulating, and then hit the "Play" button to load the DOL again. When you load the save file, the planet just disappears.

Dolphin 3.5 and 3.5-367 are old versions of Dolphin that have
known issues and bugs, so don't report issues about them and test the
latest Dolphin version first.
Which versions of Dolphin did you test on?
The DVDError doesn't actually happen on 4.0-4418 but when I switched from 4.0-4843 to it, the disappearing still happened. I couldn't get it to trigger just using that version though.
Other then that, 4.0-4748 doesn't seem to trigger it, but 4.0-4800, 4843, even the latest version with 4.0-4877 do

Does using an older version of Dolphin solve your issue? If yes, which
versions of Dolphin used to work?

What are your PC specifications? (including, but not limited to: Operating
System, CPU and GPU)
Windows 8, Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz, NVIDIA® GeForce® GT 635M with 2GB DDR3 VRAM.

Is there any other relevant information? (e.g. logs, screenshots,
configuration files)
I've tested with 2 different NAND dumps, and I've been able to replicate it somewhat consistently (might need to do that process 2-3 times for it to happen). I'm using D3D with default settings, and OpenAL with HLE for Audio.
