This is ringing alarm bells for me... bearings may be moving and not aligned properly causing premature wear. Wheels Manf BB may help to secure the BB with its screwed together nature. I have also never heard a good word said about any fat E13 BB/Chainset....... I can literally remove and press in new BB with my bare fingers....
There is a chap on YouTube called Hambini, he is rather loud and there are many expletives, but he has many videos that demo issues with frame PF alignment / bearing seat tolerance issue. He also sells machined BB's that try to overcome these issues
