[BUG] 20x Max Plan User Hitting "Extra Usage" Limits After Single Session - Severe Regression

What's Wrong?

As a 20x Max Plan subscriber, I'm hitting "extra usage" limits after only ONE chat session, with the limit resetting at a specific time (6pm Europe/Istanbul). Previously, I could run 10+ parallel Claude Code sessions simultaneously, complete multiple tasks, and never encounter any usage limits throughout the day.
This represents a severe regression in service quality for Max Plan subscribers who are paying premium prices for higher usage limits.

Key Observations:

1. Only 155 tool uses across 9.5 minutes of work
2. Session completed only ONE task before hitting limit
3. Error mentions "extra usage" - implying there's a base usage + extra usage separation
4. Limit resets at a specific time (6pm local time) - suggests daily quota system
5. Previously could complete 10+ sessions with hundreds of tool uses each

What Should Happen?

Historical Performance (Same Account, Same Plan):

• Could run 10+ parallel Claude Code sessions simultaneously
• Each session could use **hundreds to thousands of tool uses
• Could work for hours without hitting any limits
• No "extra usage" concept existed or was never triggered
• No time-based reset mechanisms were visible

What Max Plan Should Provide:

1. Unlimited or very high usage limits consistent with the premium tier pricing
2. Ability to run 10+ parallel sessions as was previously possible and documented
3. No artificial throttling that prevents normal development workflow
4. Clear communication if limits have changed from previous behavior
5. Accurate token tracking (current session shows "0 tokens" which seems incorrect)

Error Messages/Logs

Steps to Reproduce

1. Prerequisites: Be a 20x Max Plan subscriber
2. Start a Claude Code session with model opus 4.6 default 1m context
3. Use the session normally:

• Make tool calls (file operations, code generation, etc.)
• Complete a moderate-sized task (~150 tool uses)
• Work for ~9-10 minutes

1. Observe: After approximately 155 tool uses, receive error:

``
You're out of extra usage · resets 6pm (Europe/Istanbul)
``

1. Attempt: Try to continue the session or start a new one
2. Result: Blocked from continuing until the reset time (6pm local)
3. Compare with previous behavior: Same account previously allowed 10+ parallel sessions with no such limits
