40 x 50 custom Map errors - has anyone run into this?

[Ironwulf]

I recently designed a large 40x50 map for a battle I was designing.
I placed my troops and completed the design.
I ran the battle but found that the sides had incorrect setup zones for free deployment. I should have setup the armies with army 2 being army 1 and army1 being army2. But rather than re-do all the 100+ battlegroups, I decided to look for a way to tell the game that Side 1 should start at the top of the map and Side 2 should start at the bottom during Free Deployment.

So in the xml file for the scenario I found the relevant line:
[hexsideterrains
map cols="40" rows="50" oddcolsstarthigher="1" oddcolsendlower="0" side1edge="3" side2edge="1" deployzonesize1="5" deployzonesize2="5" tileset="green"]

So instead of side1edge being '3', I changed it to '1' and changed side2edge to '3'.

That's when I noticed an issue when zooming out on the map during actual gameplay (it never errored out during the design phase). If I zoomed totally out to max view, the game would freeze up and throw me an error. If I scroll off the map it also errors out.
I think it has something to do with my mouse being at the edge of my screen.

Anyone have any ideas? Has anyone seen this before in a custom scenario?

Should I just rebuild the whole thing?

Well... the fix was to simply redo it all!

So I have.

The scenario covers the battle of Dyrrachium-Lesnikia 48 BC (Caesar vs Pompey in Illyria), and is intended as a 2 part mini-campaign.
If you feel like playtesting this - look for my postings in the game.
