The Bug
When a minecart derails, it turns the opposite way from where it was facing in all directions (north, east, west), except if it was facing south, in which case it will not visually rotate when derailed.
This is most notable with the minecarts listed below, as their model noticeably rotates. See Jingy's pinned comment below.
- Minecart with Furnace
- Minecart with Chest
- Minecart with TNT
- Minecart with Command Block
Note: This does not affect the player-facing direction when in a normal minecart while it derails, however, the minecart itself does still rotate in the circumstances listed above.
How to Reproduce
- Place two sets of rails (these can also be powered rails) around 5 blocks long, one going north-south, and the other going east-west, some distance apart.
- Place one of the minecarts listed above while facing east, and then push it. When it details at the end of the track, note how it faces the opposite direction. Repeat this for the north, south, and west tracks.
- Note how only the south-facing derailed minecart does not rotate.
- Trying this with the other minecarts yields the same result, however, with some minecarts (such as the normal minecart), it may be hard to tell the difference.
