[BUG] High usage while using Opus 4.6

What's Wrong?

High session usage!

What Should Happen?

I ran a single action which was to sign a .pdf and put a date on the form after having my usage exhausted this morning and being shutdown for 5 hours. That action took up 13% of my five hour usage window. That is not expected for a Pro Max user. This has been occurring for two days.

Additional Information

This is an issue that has gone on for two days. No matter which version of the model I use i am seeing extraordinary session usage that does not correlate with my daily or weekly usage. Fix your stuff! I have hit usage caps and it seriously limits my productivity and i am performing basic functions in depricated models. This has not happened in the past. I have never been near my limits.
