So, when rocket miner launches, it flies to 0 0 coordinates.

But moreover, if i try to launch second rocket miner, it also flies to 0 0 coordinates, lands on the first rocket miner, starts mining and breaks it. If i wait till the first miner is done and then launch the second, it will also fly to 0 0 and start mining down already mined and empty mineshaft.

In case with a single miner, after it's done, it flies to x 0 z 15, next time to x 15 z 15 and so on.

All miners are fully equipped and have a miner remote with refueling position set.

IC2 1.19.2-2.0.8.1

ty.
This bug happens if the position is the exact same as the rocket miner stands on.
Simply use a different home position as the starting position.

This will be addressed next patch.
(I will simply disallow the home position as the start position)

Okay, thanks for clarifying. There is another issue #939
