[bug] saved weapon builds bug

So im literally able to build a gun with my saved build like 1 out of 10 times, other times its just a blank page in place where build are supposed to be. I can tolerate any bug but this one is so fucking annoying, is it this hard to fix for years since this function release? Anyways clearing cache does nothing for me, is there any other fix? Because i see streamers use this function and it for some reason works
