Issue description:

I was playing my world and i had a refined storage system already set up. I made a wireless transmitter and added that. I then made a long cable leading to another place seperate from my base and i put another wireless transmitter there and added range upgrades. i tried to use it with my wireless grid that worked before but it wasn't working for the new wireless transmitter. I logged off and now when i try to load into the world it crashes. I also had a crafting system to craft supremium essence set up but it wasn't running at the time so i don't know if thats relevent.

What happens:

Press play world
Crash

What you expected to happen:

Play world
be able to play ideally without crashing
