I can not reproduce it.
But it looks like others found the same problems and even more games are affected: https://forums.dolphin-emu.org/Thread-disappearing-objects-dolphin-4-0-95

It seems that MMU Speedhack got busted by one of the commits.

Cursed mountain Wii is also broken after this revision. It had an issue in the past where the game would crash at the first autosave attempt ingame and could only work with mmu enabled, was fixed in the process and didn't need mmu or it's speed hack to work, and now after this rev it crashes again without mmu enabled (and i am not talking about mmu speed hack, just mmu which makes it speedwise unplayable).

Ok, another regression, Def Jam Fight For NY worked with mmu speed hack fine before this revision, now it needs MMU with jit or text is missing. Jitil is also unaffected.

And fzero gx is fixed with jit64 with mmu also, thing is it never needed the option and it works fine with jitil without it (just the mmu speed hack is enough).

MMU fixes it just because it disables fastmem.
I'm sorry I haven't dealt with this yet - I think I know the cause, but I've been exhausted the last few days and unable to work effectively.
Updated by kostamarino over 10 years ago
All of the issues mentioned here are fixed in latest master.
PS.Sorry if i sounded pushy comexk, it is just that i tracked a lot of issues lately, and one of them even made the work i do with gameinis more difficult and i got edgy.
