I’m assuming this is something to do with local caching, but I logged in from a computer I’ve not used in a while and a few patrols (and thus their members) did not appear on the roster. Clearing the local data and reloading fixed it.
@graywh - that would be correct and a hard refresh would most likely have done the same. cache and cookies are a natural part of web browsers. So what would be the bug ?
