What happened?

The game gone well for long time (and at least 3 releases) since it no longer loaded the savegame. The world is midgame, many mods are fully done. By watching the crash log i think is an issue about Extreme Reactors turbine (maybe redstone port). I removed shaders and everything graphic related also because oculus is reported too. There are 2 turbines 7717 with an insanite coil made of 24 blocks and some reactors, fluidifiers and reprocessors to archieve to get needed materials. The related questline is fuly done.
If i start a new world everything works well (at beginning because i not tryied to play so long time in the new game)

Update: I modified settings before loading the game and i removed every graphic feature and set all graphic parameters to the lowest possible and the game loaded the save. Then i set all to the default in game and all worked well. After 2/3 sessions the problem is back, with the same error, randomly. I shut down the game and the day after it not longer loaded the save and crashed. The save is not corrupted because i was able to resume it when i lowered al the settings.
So i tryied again to lower settings and the game, again, loaded with no problem, then same procedure...
The issue appens when my induction battery is full and turbines are managed by redstone, so they start and stop depending on the buffer level. I used enderIO cables to connect the ports

Update 2: when i'm gone to check the turbine i saw enderio redstone conduits was invisible and other pipes/cables from mekanism was graphically disconnected in the turbine chunk only.
Now i removed all conduits and replaced it with morered wires.
I had some trouble with conduits before in ATM9 No Frills (really it was the same issue, but i suitched modpack and i forgot that since now) and i think the problem is caused by enderio.
I'll check if without using it i'll get the issue again
