Hi, this bug is still persistent for me, even in the new updates.

Below is another example to push this issue again, also to indicate that this issue still persists on v2.1.117

It got to 22k tokens within a minute or two, then it hung there.

Bumping again, executing a plan. It shot up to 14k tokens quickly and then froze there again. Right now it is on medium effort.

Why on Earth did I resubscribe to Claude Code. Sigh. Whenever I sign up again, it's just a constant shitshow of debugging issues like this.
