I am hosting and playing a minecraft server with project red installed, bandwidth and latency is not and issue, as I am hosting it on a local network.
In single player I can shift-rightclick a block (with any screwdriver) and it will spin, but I cannot do this in multiplayer.
Regular right clicking with a screw driver works.

Behaves as expected on 1.18 multiplayer:

• Normal right click rotates gate
• Sneak right click goes through different gate modes

i'm currently experiencing the same problem

i'm running a local 1.12.2 minecraft server on forge with latest release of projectred available on curse/twitch

whenever i hold a screwdriver i can rotate any gate by right clicking on it but i'm unable to change its configuration by sneak+right clicking.

This also only happens when i'm connected to my server and everything is fine in singleplayer

I have found nothing about this issue on the web nor inside the config files (maybe missed something?)
