I have a bottom bracket that was cross-threaded once. I had the threads chased, replaced the bottom bracket and now it is cross-threaded again. How many times can a bottom bracket's threads be chased? Is it worth trying to chase the threads again? I really don't see any other option, but just wonder if I have already used up my allotted opportunities to do this and am now at the point of diminishing returns. Thanks in advance for any advice.
