wrt "nuclear weapon" -

​​​​​​

have observed that the makers of these chainsets take good care with the threads on the mounting boss as well as those on the chainwheel such that the chianwheel's pattern will come out symmetrical with relation to the long axis of the crankarm when fully cinched down ("clocking")

in this case that registration is clearly off

it might be that disassembly when paired with cleaning & lubrication of threads might permit chainwheel to cinch down at a symmetrical position
