## Description of the bug
Tackling someone buckled to the m56 always puts them on the tile behind them, even if the tile is unvaultable (example: barbed cades)

## What's the difference with what should have happened?
I expected to be let down on the same tile instead of being sent past a tile that I can't climb over

## How do we reproduce this bug?
Step 1) Set up the m56
Step 2) Buckle yourself to the m56, with a barbed cade behind you
Step 3) Get tackled off of it
Step 4) See yourself on the other side of unvaultable cades
