I created a ticket https://openxcom.org/bugs/openxcom/issues/1369 (pathfinding is wrong for grain field), but can't attach the example files. I'll leave them here for now.

for traceable straight lines, we use bresenham stroke, otherwise we fall back to A*.
bresenham finds the most direct route, A* finds the most TU-efficient.
this is why you're seeing this difference.

Just to clarify: Grainfields have a higher TU cost to traverse than grass (6 TU vs 4 TU). Thus, given the opportunity to skirt it, the second path walks on the grass beside it, then around the wall through one tile of grain. In this situation, you might have troops in Flying Armor go up one level and fly over the grainfield and land on the otherside as their preferred path, as well.

I know they slow you down. The game picks the slower route, and I considered this a bug.

Why pick direct path if it's slower?
P.S. And my question here was "How or where to post files, if I need to attach something to a bug?"
-
to attach something to a bug report, you need to be logged in when you initially file the report. this was filed by "guest" so it's not possible

Is only the original poster allowed to attach?

yes
