Twice in the last couple of days I have been gunning out of a LAAT in the Clone Wars scenarios and have gotten hung in the squad spawning loading screen. The only way out is to use ALT-F4 to hard-shutdown the program.
The game itself is not hung up as I can hear all the action going on and can even use the TAB key to monitor the scoreboard as it updates in real-time.
This happens after I repeatedly hop in the LAAT. Like at least 5-6 spawns in a row.
The first time was on Kamino when the clankers were trying to capture the landing platforms. The second was on Kashyyk when the MTTs were still moving forward.
