I was recently working on a build with some roads that were closed off by 64x64 bricks and 1x8x10 bricks. I proceeded to test some events that dealt with a car. For fun, I decided to crash my car into the 64x64-instead it, went straight through it. I tried this with different speed variations, and it turns out that this only happened when I drove at a high speed. Is this a glitch? Will be updated in v17?
Oh, and I did search for this glitch on the forums-sadly, there wasn't much I could find...
