Hello. I was using a wireless energy crystal to power a ghast farm using an industrial foregoing setup. I'm running this on the FTB Academy 1.12 pack with no other mods installed.

I have the crystal connected to my power source through a relay and used it to power the mod crusher and duplicator. I didn't like the location and decided to move it. When I tried unlinking the wireless crystal, I got an error message.

One other thing I also noticed is that the wireless crystal loses its connection when I pause the machines.

I tried editing my original post, but I guess git doesn't allow that after a while.

Just wanted to follow up and say that it's not just the IF machines that cause the issue. It works fine when I unlink everything from the wireless crystal, but the problem comes up when I try to unlink individual connections.

I do know that the connections will terminate if the machine is no longer present. Does this hlonly happen on specific machines or mods, or is this on literally everything?

It seems to be happening sporadically (sometimes it does, sometimes it doesn't) on everything. On further inspection, it actually breaks when I unlink it from other crystals in addition to the machines. The error seems to only come up when I disconnect using the wireless crystal UI and doesn't happen at all with regular relays or I/O crystals.

Noted. Try unlinking them using the wrench as a workaround, as this functionality is the only one that's present on the 1.16.5 version and works perfectly fine.

Sure, I'll do that. Thanks.

The crystal UI was more of an afterthought that never really got the polish it needed. Though I thought I ironed out most of the major issues like this...

As for the crystals un-linking when you pause the machine. The crystals periodically check to make sure the block they are connected to is still valid and will disconnect after a while if its not. iirf pausing an IF machine temporarily removes its energy capability so its no longer a valid energy target.
There are a lot of little issues like this that I plan to fix when I re write the crystals in 1.16/1.18.

Going to go ahead and close this as the 1.12.2 version of Draconic Evolution isn't going to be supported anymore since the focus is on the 1.16.5 version.
