Using K-Drive Launcher on the Steps outside the Nekralisk entrance makes me fall through the map.

[Magesticer]

Title says it all basically. Just loaded into a 5-15 bounty from mother and as soon as I was outside I walked a few steps and used K-Drive Launcher. Instantly began falling through the map. Unstuck command just transports me to ground level where I start falling again. I was able to jump off the K-Drive, which  thankfully transported me back up to solid ground. Walked a few steps and used the Launcher again. Same thing happened.

Edit: Was able to reproduce this bug outside of the nekralisk area as well. It happens to me all over Cambion Drift.
