Already read the rules, and double-checked a few things. I am having this same labeled issue as the original post creator did (at least, based on post title name): Whenever I try to place the Torture Freddy Head down as a block, it with visually look like it was placed for a second, then disappear as though I hadn't placed it down at all (including ). As per someone's explanation to my query about Rule 4 in #│general , I did try a separate mod pack that is ONLY GeckoLib, Surveillance Package, and the MW mod itself. It is still acting like this.
