Looks like this bug also occurs in win-build or this is another bug.
All my notes in this thread relate to current win version downloaded on 2025-11-13. (the latest, unless I missed a second update on that day)
When its happened I tried to toggle build mode, menu, inventory and switch parts. Nothing had fix it.
I got it again. It happened when I moved mouse to bottom of vehicle with low level camera and high slope angle. Maybe its related to NaN or infinity in math related to place normal calculation. (I got troubles like this in my voxel game couple weeks ago and to fix that just added checking and returns upd: 1,0,0 vector if its bad)
I think I might've figured it out, the spider drones jumping might have been breaking the raycasts. I have no idea how that works but since the bug - for me at least - only happened periodically and in the Toxic Desert biome exclusively - which is the only one with the spider drones - I have to assume its that.
I disabled the jumping and it seems to be fixed for me, let me know if it were to be still broken for You
This is the most baffling bug I've ever encountered, so thanks for helping me out
As I mentioned earlier(sorry if too vague), I saw exactly moment when last bug was happened.
It occurs inside editor when I moved mouse over horizonal face when mouse vector and face almost parallel.
I see no other causes related to zone or something else but new part position and facing calculation based on face normals. I scry it caused by Tan and too large precision error in formula.
Sorry if my English some times too obscure.
