This was occurring for me in FE 1.32 as well. I now have it in LH.

Could someone who is seeing this provide their debug.err when they see it.  I suspect you are running out of memory but I would like to be sure.

If its reproducable in a save that would be even better.  But I suspect that from a fresh reload the issue will go away (this would further confirm that it was a memory issue).

I have a save game, but it isn't reproducible after reload.
Will grab debug.err if it happens again.

Please link a debug.err from a game having the issue.  In the one case we saw the person was running 8x anti-aliasing.  So if you are also runnign 8x anti-aliasing try setting it down to 2x and see if the issue goes away.

Most people use dropbox to pot it here.  Also could you try switching down to 2x or 4x Anti-aliasing and see if the problem stops happening?

Ok, just had this issue in 0.51.

Have 8GB of RAM and wasn't playing too long in this session. Actually, i only recently reloaded. Also, never had this issue before in either 0.50 or in FA. Restarting game fixed it. Unfortunately, I saw too late that you guys need debug.err file. I'll provide one if I run into this again.

Btw. I have played on huge maps in FA with Stromworld mod and 28 factions in one game. Even after 500 seasons it was running smoothly and no memory issues. I seriously doubt its low memory issue here.

Edit: I also remember that steamer MadDjinn ran into this on his first play of LH. Actually he had it at the very start of the game. So I really really doubt he ran out of memory at the start on a large map with 8 factions.

Edit2: Here is a link to a recording of that stream - http://www.twitch.tv/maddjinn/b/380965967 . It's around 15-th minute that he ran into it.

Thanks for doing that.
