We are aware of log spam issues but have not found solutions for all of them yet, I’ll be taking a look soon.
In future, please be sure to note what Monolith zone you are in when you experience a bug so we can better diagnose the issue. It appears you were in Forlorn Streets, is that correct?
Since the game crashed, please check if there are any files in C:/Users/YOURNAME/AppData/Local/Temp/Eleventh Hour Games/Last Epoch/Crashes and upload them. It might be related to the length of the game session.
Thanks for the report and your patience while we investigate these issues.
