BUG - Kicked on using L-Shift to stand up

In my plugin, a player is placed in last stand when damaged enough. It used to be that the only way the player could stand up was to be picked up by a friend. Now though, with the Horse update, the player can use L-Shift to stand up. This causes a bit of a bug where the player is detected moving illegally, and is kicked from the game. There are a few solutions that I have thought through to solve this issue, yet I do not know how to implement these:

- Disallowing the use of L-Shift while the player is in last stand
- Cancelling the stand-up event (which I have yet to find, don't think there is one)

This one I know how to do, yet it is a last resort:
- Cancelling the kick and re-sitting the player down.

Does anyone know how to implement any of these (preferrable without the use of NMS/OBC, but as a last resthose are acceptable)? If so, it would be a great help!

 

Maybe, i am not sure, but maybe you can do something with VehicleExitEvent to cancel the Shift Exit

 

I'll definitely look into it and let you know if it works.

EDIT - It worked! Thanks... I thought so.. new problem. I will bump and add the new problem to this thread.

 

Alright, new problem. The vehicleexit event didn't work, so I just moved up the entity to which I was making the player sit on (an arrow) 2 blocks up. The new problem is that not only does that seem to work (even when cancelling the vehicleexitevent), but it kills the player... does anyone know of a way to prevent the L-Shift cleanly or to make the player sit in another way?
