**Describe the bug**
Doing .ultimate_ on a chainladder model, I'd expect the figures to match the final column of .latest_diagonal_ . However it does not. This seems to occur when there are missing v…

Build this out with something more basic than https://institute-and-faculty-of-actuaries.github.io/mlr-blog/ but referencing perhaps https://chainladder-python.readthedocs.io/en/latest/

If I want a volume all, or simple all set of link ratios a call to ata(paid.tri) works fine (where paid.tri = cumulative paid development triangle).
If I want to create a volume-weighted fit on the…

What steps will reproduce the problem?
1.Using BootChainLadder on a triangle with zero residuals, for example Triangle
