Modpack version
0.4.8 via GDLauncher

Describe the bug
The hotkeys to change between Storage Scanners was not working consistantly,
I put the tablet in my offhand to see if it improved the situation.
It overwrote my hotbar slot.
I had another user on the server test and he lost some gear.

Steps to repeat.

1. Link two Storage Control Screen Module's to different Storage Scanners.
2. Insert into @RFToolsStorage tablet.
3. Put device in off hand.
4. Toggle between them using hotkeys (default of [ and ])
5. a copy of the tablet overwrites your active hotbar item.

Thank you for the report, I will investigate the issue.
