I just geomerged a double block nearly perfectly into the wall of the Crypt. There's a catch though, I had no braces except one Large Block, no round restarting, no interlocking the objects and grabbing it. All I did was try to place it next to the Large Block and it just sunk into the wall of It's own will. I forced the block out of the wall (it tried very hard to go completely through the wall and disappear,) and tried it again and was able to reproduce the same effect exactly as I had by accident the first time. Now, I didn't save the map or anything but I'm wondering if anyone else has noticed the same thing happening in the Crypt or in any other areas on Sandbox or other maps. Also is there a possibility that this could lead to a way to geomerge on Sandbox without all the messing around? Atleast in the Crypt? Some of you may laugh at this, but I just figured I'd let you know, since I've never seen that happen before.
In the dunes of the middle level, if you spin a double box around a little bit, it will geomerge into the dune and you can move it around freely.
That glitch is commonly known because it happens all the time. I have never used it in a map or tried to. it is very inaccurate.
I've had it on the floor of Sandbox, with a Huge Block I was using for a guide to merge two other blocks, but it sank clean through the floor - and worst of all, it was still in the map, so I had to glitch under and find the teardrop to delete it. Hadn't saved my map in quite a while :/
