When playing lan, if connected player opens GUI of Sequenced Gearshift it also opens for host, where host can't manipulate with it and has to close it every time.
Steps to reproduce:
Play Minecraft 1.14.4 with Create 0.2.2a
One player hosts lan game
Other player joins
Joined player tries to open Sequenced Gearshift GUI with RMB
Host also sees GUI for no reason and tells connected player to stop messing with it

Here's a GUI I'm talking about:

Can you confirm that this a lan issue and not a general server issue?
I can test this in a couple hours myself in case that you don’t want to set up a local server.

Just tested it for dedicated server – no troubles at all, only one player sees GUI upon click.
Probably, something to do with client/server splitting for lan player.

Also, Botania shares some troubles with lan – host can see torch count when client uses manasteel pickaxe's right click ability, but this should be posted on their github page :)

Looks like it was fixed in a recent update and you forgot to close the issue, so i'm doing this.
