Yeah, your save is very helpful! I still don't know if I can fix it, but this will allow me to look into it deeper.
Since I wasn't getting these glitches, maybe you could try playing on a normal dolphin build with rather normal settings and the distance mods. Just to see if they happen. It's possible I didn't play enough.
yeah I'll definitely try that.
It is actually very unfortunate for me. Because it is very hard now go back to the old Lod, everything looks so ugly without your hack :'( But at the same time it is not possible to finish a 1 period without these glitches ruining the game, not talking about full match.

wow, some interesting things happening!

So to re-answer your question again, now running the game with the latest MASTER build:
1. Check if just this code causes any visual glitches
048170C8 4AA00000
The game runs without any glitches at all!
The player models and side benches don't run at the higher possible quality tho, during the actual gameplay.
2. See if this small modification does anything different
C2D96FE0 00000002
80820000 90830090
60000000 00000000
048170C8 4AA00000
043421C0 0003020C
This modification makes everything looks at best quality, but
all the glitches occur again.
Also regarding the crowd.. when you don't press any button as the game starts, "demo mode" start and in this demo mode the crowd is actually moving even during the actual gameplay!

This happens with or without any hack applied.
Great that helps a little bit. That's a good clue for the crowd, maybe. I'll look at it.
Nope. With your suggestion and with pausing the game during face-offs to get the crowd moving until the puck drops, I have the perfect points to look for crowd animation triggers, but it just isn't getting me anywhere. I don't know if it uses the crowd animation memory region for other things during gameplay. Plus the game is really sensitive to the debugger, crashing often.
Damn! Sometimes I really hate that game

What now?
I'll continue working on your savestate and see if I can figure out the LOD stuff.
