So I've made a cobble gen that uses immovable blocks to keep pistons from pushing each other out. Originally I used obsidian, and it works for the most part. However, there is always one block that disappears without reason, which breaks the design. I've tried changing the block type (the most recent one was a furnace) but I still have the same issue. And no, I'm not co-op'ed with anyone, nor do I have any island partners. I'm the only one with access to this account and this island. I've even let staff know (rinn, I think?) about this once in chat, said that they have never heard of anyone having such an issue.
