Every time i join the server the pistons stop working with signals from red-stone pen circuit lines. i have to put a separate block in the place of pistons every time and have to make a block update at that position then again place the piston in that place to make it work. its really really problematic.

Hi, oky, can you give me the version of the mod/minecraft, and if it's forge or fabric (best the complete JAR file name) for reproduction? Should not be a big issue. Cheer's;;

Yepp, saw it in 1.20.1/1.20.2, fix versions are redstonepen-1.20.1-neoforge-1.3.22.jar and redstonepen-1.20.2-fabric-1.6.24.jar.
