Using the latest versions for LT and CreativeCore.

1 - The first one is that most shapes for the hammer are broken. Trying to use Line, Wall, Sphere and Cylinder always result in the Dragbox selection.

First click:

After second click. Instead of the Wall it makes a Dragbox:

2 - The second one is that I made this floor and wanted to sneak+middle click to pick it up and place it somewhere:

But when I place it snapped to grid, this happens:

Placing it between 2 blocks:

Placing it between 4 blocks:

The issue happens when picking it up by sneak+middle click and extracting from a Recipe. The block is made in the 32 grid size. Here's the file for import:

Floor.txt

3- Lastly, mark mode is not placing correctly:

Here the block is snapped to the grid by holding sneak:

When I press M the center of the block relocates to the corner:

3rd problem also occurs before pre85, when i performing copy of something (with mirroring and placing to non-flat surface) and try to place with fixed positioning (like same structure on another side), it always shifted on 1/2 block.
Actually it happening due to placing inside cuboud (no free space in it), solved by markmode.

@Dushess That problem was actually fixed past pre85, it's just happening again. It's not as intense as it was before, tho.

All of them will be fixed in the upcoming pre-release.
