[Bug] Excessive token usage in Claude Code 2.1.1

bug details
Starting this morning with the update to CC 2.1.1 – usage is ridiculous. I’ve been working on the same project, same routine, same time, for months. But today it hits the 5 hour mark 4+ times faster! 2x usage was promoted during the holiday season, but current usage is much higher than 2x. I’m already at MAX and even before today – I usually never reach the 50% weekly cap. Now from today onwards it is becoming ridiculous.

It seems like running a plan mode in Opus it literally ate 10% before my eyes. Without reading the entire database.

It seems like Heiku is not affected as I was able to use it for about 1 hour and get 2-5% usage.
