AE Rev Bug - Mine car incorrect path logic

[rozniak]

Found in build: 71dc17d
Last working build number: N/A

Description of issue:
When holding a direction key, the minecar is (usually, with some exceptions) supposed to follow around corners automatically unless heading in the opposite direction.

The logic is incorrect for the up key - when held, it will traverse corners as normal, however upon travelling left and coming across a corner downwards, the minecar will pause then start travelling right until coming to a stop on the right downward corner.

In the original game the minecar does not travel back to the right, the direction it was previously travelling.

Steps to repro:
Attached is the same save file from #1141 - travel over to the vertical track on the right hand side of the screen. Now hold the up key, the minecar will hit the ceiling and correctly travel left, then upon hitting the left wall, it will pause and travel back to the right. It comes to a complete stop on the left in the OG.
