[Bug] Premature session closures after recent update

Bug Description
Since the last update I have been experiencing extremely significant pre-mature session closings. What this translates into is 1-3 hours of work, instead of a day or more. I have checked and this is not a product of plan usage limits or context overload. can you roll me back to the previous model and let me see if it changes.
