Is this still an issue ?
This issue is still present in the game. However, I thought it might be helpful to clarify that it's caused by how the collision box (or object footprint) has been coded for grills vs. counters (in all cases, not just this specific stuff pack set). Grills have a portion of their footprint set behind them:
Counters, since they have been designed to align with walls, have their footprint extending in front of the object only:
This offset is why they do not want to line up together. When the counter's position is reversed, the footprints then sync up and the objects can be automatically aligned.
I wouldn't really consider this a bug, because the new counters and grills match the same design as prior counters and grills. I think what's new here is the matching design style and the way this grill has solid ends that look like it *could* be intended to align with counters. However, unless Maxis decides to change the footprint for grill objects (and I think they should consider it, as I don't see utility in having that footprint behind the object), you will need to use the ALT key to align them manually.
let's say it's present in game and as i thought before possibly the design of it but BryonyRae hit the nail on the head , if one places the grill as is you will get that misalignment
using ALT to align it works i don't think it is a bug and is working as designed
