Does a large battle cause a lock up?

[NTJedi]

I believe the battlefield limit for units is almost 6000. If the game keeps locking up on you then it's very possible you've reached the limit.
Only one spell can save you: Flames from the sky

If you can't cast this spell... then you'll have to go with the theory that some nearby sun went supernova destroying the planet.

**Hopefully the battlefield limit will be increased for DOM_3**
