Hello!
I found the new Alpha Build 2 for BC 8.0.0, and decided to give it a shot.

The Engine Texture is glitched and names messed up, but still functional. I placed one down, and shift-clicked coal blocks in; it crashed my game.

I did the same in a combustion engine (to move around inv), and crashed game.

I tried again in the Quarry Block, and it, again, crashed.

Not sure if you're "looking for" bugs yet, just thought I'd put this here (in-case you didn't know!)

Thanks for all you've done, and can't wait to mess around with the final release!

as seen in the reference above, the issue not only affects engines but every shift-click interaction. #3468 were two issues so i referenced the shift click here to get a clean, separate issue

I tried again in the Quarry Block, and it, again, crashed.

When? What you was doing?

I opened the Quarry (as it now as a GUI in 8.0), and wondered if the new items are a filter. I couldn't put anything in, and tried shift-clicking, when it crashed.

You should put frames in it

Ah, okay.

Should be fixed by the commits mentioned above.
