I had problems with my TE duct network (stopped delivering energy all couple of minutes),
so I built a circuit with autonomous activators to replace a conduit automaticly to reset the TE network.
Now, to catch the broken conduit item reliably , I used a buildcraft obsidian pipe to be able to replace it again.
Directly above this circuit, in the first floor, I have my ME-Access terminal.
Picture:
Code:
[ME Terminal]
------------------ floor (stone)
------------------ floor (stone)
------------------ floor (stone)
[TE conduit replacer]
But whenever I broke a block with my pickaxe when standing in front of my ME access terminal, there was no item floating around to pick up.
The broken blocks were gone.
When going some blocks away, it worked like normal.
Also, it suddenly begun to make that sound when a block is picked up. It repeated every 2 seconds, while there was no item around which I could possibly have picked up whatsoever.
So I thought it was a bug and restarted the FTB server.
But the pick up sound remained in the direct vicinity of the access terminal and at this position still no items could be gathered when breaking a block.
They vanished somehow.
I thought: "What the heck ???"
2 days later, I visited the circuit with the autonomous activators again for some reason, and noticed that the pick up noise got louder than in the first floor.
So I checked the circuit. And then realized what was happening:
The vanishing items and also the cyclic pick up sound were not bugs.....
The obsidian pipe (in the basement, directly under my ME system) was sucking in all items that fell on the floor in front of the ME terminal and
added them to the "TE conduit replacer" circuit. So one autonomous activator tried to place those randomly gathered items
instead of the TE conduit, which caused the cyclic "pick up" sound. (because the item could not be placed, but fell down and was sucked up again from the pipe, was placed again...)
I simply did not know the obsidian pipe had such a big range and could also suck items through a 3 blocks thick stone floor.
Man, this one completely bugged me out. I knocked my head on the table when i found the reason after 3 days.
There were 2 geothermal generators, some ardite, emerald, random blocks and other stuff circulating around the circuit when I checked those inventories.
