What's Wrong?

Claude suddenly reset my 5hr window by suggesting limit used but the return time was set for almost 6 hrs from the time the reset was applied.

This is very strange because, my then current session had 1 hr remaining to session reset. This made me wait 6 hours (from the time of reset).

What Should Happen?

Session should only restrict you from the sliding window of the session not 5hrs from the time when claude perceived the 5h session limit is reached.

Error Messages/Logs

Steps to Reproduce

Use claude code normally
Burn tokens upto for 4 hrs with 1 hr remaining for the 5hr window.
Burn up to 100%
Usage restricted for 5hrs from the time it hit 100% not 1 hr because 100% is reached at 4th hr of the session.

Claude Model

Sonnet (default)

Folks please roll back you prompt cache and cache invalidation feature, I am pretty sure this is the culprit it is burning tokens like crazy went from 17% to 99% in under 30mins with Sonnet on Medium effort. This is unreasonable.

I am super frustrated at this point, it burned through the 30% of weekly limit doing the same things it did by burning through 4% of the limit. There is definitely something goofy going on. Either the scheduleWait is not working or Cache invalidation is getting messed up. On this new version I see cache invalidation time as a new feature and getting automatically set to 60mins and then decrementing and then going back to 60 mins in about 10-15mins. (I am not sure if that is causing this issue)
