## Description of the bug
Tumbling against someone manning an M2C/M56D won't stun or affect them in any way.

## What's the difference with what should have happened?
Should behave as normal tumble: push one tile and be stunned for 1.5/2 seconds on the floor. In case this is intended, makes no sense a one ton rhino alike creature is unable to tumble against a lil machinegun. Or at least throw its user.

## How do we reproduce this bug?
1. Put one of your sides facing the said user.
2. Tumble in his direction (maximum two tiles).
