When attempting to access the UI for a solar generator, it just corrupts the Client-Side display of their inventory, requiring a rejoin to fix.

This seems to exclusively a multiplayer issue, when connecting to a dedicated server you cannot access the gui of a solar or wind generator and attempting to do so corrupts your inventory causing items to duplicate and overwrite other items.

There are no mentions of anything happening at all in either client or server logs

Also occurs with the Metal Former, doesn't affect the energy bridge or wireless node.

Finally got an error of some kind:

Confirmed on a dedicated server using no mods other then JEI, Mantle, and Journeymap installed.

Replication involves starting a dedicated server, joining with a client and attempting to access any machine from AcademyCraft.

Fixed in next beta release.

Issue not resolved in beta3 release, can't open UI of wireless Imag node without corrupting inventory as before.
