I've added this to all of my skin user's manuals, but thought it deserved to be posted here, as well. This may or may not apply to other skins, but it certainly applies to all of mine - Atom, Jupiter, Mercury, Neptune, Saturn, Triton, and Venus.

After installing a new version of the skin, you should never make existing albums from the command line or the multi-maker. Skin updates often involve new or changed variables, and the skin makes needed corrections when the project is opened in the regular application. These corrections don't occur if the project is made from the command line or the multi-maker, which can result in undesirable results or even catastrophically bad results.

At a minimum you should open each project in the application and save it - a quick CTRL-S will do the job. That will ensure that variable corrections are properly made. After doing that, it is once again safe to use the command line or the multi-maker.
