E6 0.4.8 (official server)

I have an elite centrifuge (multiblock) which occasionally becomes inaccessible when right clicked with an empty hand. It sometimes works as well though, and I have not been able to identify what the difference is between when it works or doesn't. I have used a waystone to leave and come back between each time when it works vs doesn't though.

It is always usable fine when holding an item, and I've repeatedly switched between using an item and empty hand to test that it's not just losing power or something. (also has full power showing)

I've posted to the Resourceful Bees mod issue tracker here: Team-Resourceful/ResourcefulBees#193 but am also posting here in case it's some sort of interference by another mod.

Screenshots
Here's a screenshot of the setup, though at the moment it's working with the empty hand

This sounds like #667 because we haven't been able to reproduce this on atm 6 or in dev.

The only thing we check that the player is holding is an item with the fluid capability such as a bucket or a tank like meks otherwise it will open the gui.

Could you by chance provide your logs when you’re not able to get the GUI to display? The issue gravy referenced shows the logs display a message that the menu/screen couldn’t be created. I’m curious to see if that shows in this case as well.

I'm not sure I would be able to identify the appropriate logs from when this happened previously. If it does it again, I'll be sure to provide them.
