The 'official' place to report bugs is the Ludeon forum: https://ludeon.com/forums/index.php?board=11.0
Or just tell me here.
This is an issue we had once long ago and fixed. The game won't log more than 1000 error messages. If it is, it's possible a mod is going around our logging limitation by accident and spewing errors, or there's some deeper bug we missed.
Can you post your mod list? And what version are you on?
