i am having the exact same issue as this user on curseforge except im in 1.18.2 on a completely different pack. exact same ghost blocks. starting and stopping a contraption turns it invisible, right clicking on the blocks makes them visable again. placing a 3 long belt only the end is showing not the start or middle. has anyone come up with a solution for this? im running this mod pack on a server, https://www.curseforge.com/minecraft/modpacks/struxnet-server-pack

Please follow the bug report template, if this still occurs open a new issue

relogging clears it but its a major hassle

seems to be related to create deco and create additions

correction its only happening on server, only mod is create

still having this issue however its not just create contraptions, its also the eureka ships not rendering in as well.
