Thanks. For seeing the system at many time points that would have been way too tedious so I just modded hyperedit instead: https://github.com/Ezriilc/HyperEdit/pull/67
Turns out that Plock gets really close to Neidon in the year 23251. Lining all the planets up only happens on the order of thousands of years. They start out with a really good alignment actually and it takes over a hundred years to get back to something resembling that, excluding Plock.
