Arbitration Defense on Lua Issue

[Lefract]

When running an arbitration defense on the Lua tileset, if the defense target strays too far away from the center of the map (when the floor gives way), they will get stuck up there and won't come down to the new floor. This drastically distorts enemy spawn rates and behavior, leading to the (full/partial) stagnation of mission progress.

This will happen if the target is following a player that is roaming around the outside of the room when the floor drops.

I have encountered this issue in about 50% (2/4) of these missions, and the result is either:

• Waves only trickle in and take 2-3x longer to complete, or
• Waves halt altogether, and the team is forced to abort.

And remember that we are forced to wait 10 full waves before we can leave.
