Hey, is there a way to let the Digital Miner chunk loaded in 1.7.10. I know that Mekanism has a chunk load module in the higher version but i dont know if there is anything like this in the 1.7.10.

There should be an anchor upgrade.

mekanism no longer supports lower versions. I would recommend looking to external chunk loader mods outside of mekanism.

I believe the anchor upgrade exists in all versions of V9 or at least I would assume it does. If not, just use some other mod; Mekanism has been out of active development for 1.7.10 for a very long time.

Well, i know that there is an anchor upgrade for like 1.10.* or higher with mekanism but in my case there is no upgrade in 1.7.10
If i only have a wrong version of Mekanism please tell me
Mekanism: 8.1.5
MekanismGenerators: 8.1.5
MekanismTools:8.1.5

Use Mekanism V9 not V8

Can i just upgrade it without issues, or will my items be gone?

No idea wasn't part of the development team back then, just backup your world and see?

Well, it doesnt add the upgrade in the newer version so i will just use the old version so i dont need to update the server
