Angled booster rail does not push mine cart when powered.
Typically in previous versions of the game an angled Powered rail could stop a mine cart until powered by redstone signal, in which case the cart would continue along the track. Now even when powered, mine carts will not continue moving.
STEP OF REPLICATION:
- place rails so that the powered rail is angled
- place mine cart on powered rail
- activate the redstone signal of the rail
- watch how the mine cart does not move
