While attempting to add an ME interface, it refuses to use a new channel. I've checked to make sure that the cable still has channels available.

Describe the bug
ME interface not using channel.

To Reproduce
I have 26 ME interfaces, and 2 crafting things attached to a dense smart cable, leading to a p2p tunnel. The last 2 interfaces don't connect
(this was done on version 3.3.59 of Project Ozone 3 if that's relevant. It's a 1.12.2 version of MC)

28 of the 32 channels should be used, but because the last two interfaces won't connect, only 26 are used.

Expected behavior
The ME interface should be using the channels available

Additional context

Am I just being dumb?

We no longer support any minecraft version older than 1.15 at this point.

Should you be able to confirm that this issue still applies to the most recent version, please update the issue and we will reopen it.
