There's multiple trains/lines that use the wait/turnaround stations in the picture, such as the corn train in the image. They all unload at the same station and they can findpath without issue.
Only the veggie train line has multiple trains and they are the only ones the seem to trigger this bug.

Added a 2nd train to the Fruit Line and now it can also forget it's pathfinding.

Managed to replicate it again with a water train line.
The key seems to be multiple trains on the line and reversing over a previous part of the path.
However the water trains aren't getting stuck like the small fruit/veggies trains sometimes are.

This was fixed in one of our previous updates. Thanks for reporting it!
