I reported an issue some months back about the Vector 4 Seater's cars spacing being too close together, even on larger more spread out turnings. Shocker, it expired. At this point, I'm just kind of fed up seeing things expired in the issue tracker, I feel like Planco 1 had better QOL stuff in regards to things like this, like how they made you use larger track pieces for the "Hydra" so the cars wouldn't clip.
I'm unsure how reliable something is if it's "acknowledged" in the issue tracker, but they've acknowledged that The Cube has clipping issues, The Pirate Ships wheels clipping through a blue texture, Prebuilt track pieces causing unsmooth transitions, and one that had previously expired but came up as acknowledged when I checked a few moments ago, clipping on the Behemoth Swing, so hopefully all these things get fixed over time.
