[Bug] Rate limiting prevents concurrent project work despite increased credits

Bug Description
Rate limit on usage, was working on three different projects (often done this when waiting on Claude), and strange to be rate limited in European time when you give extra credits (2x) because of extra capacity. The Ultrareview stoppet because of this, and no way to continue. Have to start a new one, and it used 1 og the 3 available.
