Any Additional Information?

No response

Just tried replacing the enderio.jar file from in v4.12 whit the one in v4.11 and the game loaded correctly whit everything else "as is" in ATM10 v4.12.
So guessing something happen between "enderio-7.1.8-alpha" (v4.11) and "enderio-8.0.4-alpha" (v4.12)

EDIT:
Did NOT load correctly doing this... 90% of conduit are not visible anymore. But collision box is stil there, but cant brake them. And breaking one of the one i still can see and putting it back, it does not connect to the ones i cant see..

It sounds like your conduits were corrupted somehow in v7 and that is causing v8 to crash, but that's just a guess. I'm unsure how we could determine the root cause of the issue, especially if the corruption happened before the upgrade.
I'm afraid I don't think we can do much for your conduits (unless you have a back up somewhere of your world).

If you do have a back up, please consider sending it so that we can isolate the corruption problem and properly fix it :)

I have the original save file from v4.11 if you want to dive in to it.
I have used the same world sins ATM10 v4.5, just upgrading ATM10 and then copy the world save folder over😅 And there has been conduit in the world sins almost day 1.

And as stated in the edit of my first comment, 90% of the conduits was gone only when loading the original save world form v4.11 in v4.12 but whit the enderio-7.1.8-alpha mod file.

It should also be noted that when trying to loading the world in the modified v4.12 and the original v4.12, i tried both times using the removeErroringEntities and removeErroringBlockEntities set to true... so in the original v4.12 (enderio v8) it crash, but in v4.12 (enderio v7) it loaded but was missing 90% of conduit.

But if you want to take a look in the original save file from my 4.11 world you can, no problem (just tell me where to send it).
But if you don't want to deal whit it for now, sins enderio is in v8 (looking forward to taking a look at it😎), and i might be the only one having this issue, i have no problem staying in v4.11 until 4.13 and try my world save ther if there is a small chance that my problem are related to this issue [/issues/1157]

PS hope you guys add the lights back soon... missing them😢😉
