Block placing issue

[Joe7670]

Short description of the issue.

You basically need direct line of sight onto the blockspace you're placing a block on in order for NCP to allow the block to be placed. Meaning that if you place a block against a ladder or carpet or any non-full block at an odd angle so that the block would end up placing outside of your direct line of sight you won't be able to place it while you should.

Complete output of the ncp version command (please prefer text here).

How to reproduce the issue (is it random / always happens / side conditions)?

Here is a video of the issue. https://www.youtube.com/watch?v=PinaTRyGRA0

Have you made any (noteworthy) changes to the default configuration of NCP?

No, still using Mark's config.

Do you run any other special plugins that affect game mechanics next to NC+ (adding skills, machines, adding/changing blocks, other anti cheating)?

Nope

Need to reproduce myself, but looks like this is a very good point to make.

Placing two carpet blocks on top of one another seems to trigger this as well.
