Saba siege battle CTD

I posted earlier in a wrong message, sorry for that.
I restarted my computer and tried again the same battle.
Another crash.
I upload the new log.

Such thing didn't happen in earlier campaigns with different faction.

Same again, there's a gap between last trace and crash.

Code: [View]

14:55:32.079 [game.script.exec] [trace] exec <if> at line 18836 in mods/ebii/data/world/maps/campaign/imperial_campaign/campaign_script.txt
14:55:32.519 [system.rpt] [error] Unspecified error. Please compress your error log in a zip format and upload it on the EBII technical help forum.

Could be memory or graphics related.

Ok.
After the crash, i can complete a siege battle in my AS campaign.
And, also after the crash, i can complete a field battle in this saba campaign.
I saw warnings about missing elements in the log. Could this be the reason for the crashes?

Nope, those are false positives. There's nothing wrong with the EDB, if there was the game wouldn't start.
