Aye, in Mekanism-1.7.10-7.1.1.118 the machines keep the particles showing and playing the 'on' sounds until after the work is done until I reopen the gui. Ofc they done with the work and do nothing, just being a bit noisy also tested with block update but nope, only if the gui reopened.

detectAndSendChanges?

@hisorange and it continues draining energy or just stuck in animation?

Just the animation. They operate perfectly as they expected.

This is a matter of server connectivity and less on my end - if you test out my machines on single player you'll find that they work just fine.
