When loading a save file some Logistical Transporters are disconnected. The problem seems to be connected to chunk boundaries. I successfully reproduced it - see screenshots. If the connected inventory is in the east or south chunk next to a transporter in another chunk it will not reconnect when the world is loaded

Version: 8.1.7.255
Minecraft: 1.7.10

Perhaps try updating to the latest Mekanism version; I can't reproduce this either.

I take that back- I was just able to reproduce. What's strange is that it only occurs for vanilla inventories, not mine; the disconnection issue does not occur when transporters are connected to energy cubes. It's most likely some kind of block update issue

Here's an image showing the oddity.

Not only vanilla inventories. Originally I encountered the bug with AE2 Inscribers. But it's possible that they are only some sort of extended vanilla inventories, I haven't checked the code.

I can't reproduce it on my server; single player only issue? Perhaps try chunkloading the pipes, that might help.

Fixed :)
