the scenario is the following:

• 8pm - I start building 36.000 light fighters, (1s each), order duration: 10 hours
• I logout
• 8pm - my Enemy sends 2 attacks on me, midnight and 3am
• he logs out
• next day, 6am, I login

The queue will unwind in this sequence:

• Build 36,000 LF
• Attack
• Attack

This can be avoided by customizing the cron.php script, but you can think about how to handle it without CRON.
