There seems to be a likelihood of deadlocks (turn doesn't proceed) with 1.03 on Insane Maps@Suicidal level. The AI builds a ton of units at this level.
1. CPU usage at 22% (4 cores, so it means one core appears to be stuck in a spin-wait)
2. Turn doesn't complete resolving no matter how long you wait.
1. Do something different in the turn.
2. Save before hitting "Turn"
Can't really provide a save game to demonstrate it though.
