Define "see".
I don't actually believe it got stuck the first time around, it just might take quite a while (potentially more than a couple minutes) to flush to disk.
I'll move that step to the package itself to make it more obvious.
EDIT: Hmm. The "Restarting UI" message is displayed *after* the syncs... Could I bother you for some MRPI + system logs (;dm in the search bar)?
