Description of Issue: 4th time that my creative energy cells are turning into obsidian is there a way to stop it?

(already changed the chunks they are in etc. ) Got a big buffer now aswell (2T) so I can live without it for some time but still annoying...

a random spawner turned into obsidian aswell but ill cover that myself (forgot what it was)
