Potential soft-lock when launching transport pods

[Feliphysics]

This was tested on the latest stable Rimworld version (1.4.3613) and beta multiplayer version (0.7.3).
Using Harmony, Core, DLCs, Multiplayer.
[also tested on the unstable branch (1.4.3626), same results]

Test:
A transport pod is ready to launch, the client presses the launch gyzmo, which brings it to the world map to select the destination, but doesn't select one (doing so would also launch the pod).
In the meantime, the host does the same thing, but actually selects a destination, which launches the pod.
This causes the client to get soft-locked because of a GUI error spam, since the client, at this point, is still selecting the launch destination of a pod that's not there anymore.
