It happened twice so far. Both times I had left it running. I tested it again this morning but put an anchor in it and came back to it still there.

Logged out of the game and when I came back the miner had vanished

please attempt to reproduce with a minimum set of mods

Tested with a fresh install with mek and tinkers only. The miner didnt vanish

You will need to begin adding mods back until you can find the culprit(s)

Looks like an old bug coming back to haunt - #3718

We are having the same problem on our server as well.

The way to reproduce it is the same way you make this happen-
#4676

I suspect they are linked.

The last one to go missing was crossing chunk boundaries and did not have a chunk loader upgrade.

Modpack - https://minecraft.curseforge.com/projects/towncraft

I've had this happen 3 times to my digital miners. They're about 40 or 50 chucks away from my base, and i come to check on them to change their configs every now and then depending on my demands, and sometimes i would just see my quantum entangloporter and a few cables sat there but no digital miner to be seen. :? Odd

There is not enough info to go in in this issue. It would be advised to not cross chunk borders with the digital miner.

To solve it properly it will need to be reproduced with just Mekanism

Sorry to bump this thread, but this is still present in the latest release of Mekanism on 1.12.2.

Mekanism version: 9.4.13.349

Had 3 miners in Aroma's mining dimension. Came back and they were gone. This has happened 3 times so far.

This issue is present in the Lapito's Galacticraft Modpack. This issue has not been tested with just Mekanism, however, we do not have any known configurations that cause tile-entities to despawn when a chunk unloads.

Issue description:

Players placing digital miners have their placement disappear when the chunk unloads.

Steps to reproduce:

1. Place the digital miner
2. Start the digital miner
3. Reposition/Disconnect + Unload the chunk

I just ended up disabling them entirely in my modpack because people were constantly reporting them missing.

Are they putting them on chunk borders?

They are, however I have a user that has also had one on a chunk boundary for awhile and nothing has happened to it. However he wasn't using Mekanism's anchor upgrade, he was using chickenchunk's chunk loader block instead

The placement does not matter, we tried, crossing chunks, middle of chunk, on the boundry, all the same.

Yeah, I had 3 disappear at the same time. 1 didn't cross any, 1 crossed 1 border, and the last one crossed 2.

Is there video evidence of the non-crossing one(s) anywhere?

I don't have any, no

This should have been fixed in recent releases
