As soon as I reproduce it again, I'll let you know.
I'm sure it has something to do with how I get to the site. I'll often just go to my collection url directly (
http://shmax.com/view_collection/1/50) and then login from there. It's usually right the first time (when I'm not logged in), but then I log in, get redirected to the homepage, and then pop back over the collection page it will be wrong (possibly after adding a figure). I couldn't reproduce it today using those steps, but I think it's because I didn't add anything yet.
On a related note, if I click a figure on the collection sidebar, and it takes me to the figure page, it looks like I'm not logged in (wrong site header, no package record). This may be related. As I did that both times I encountered the issue.
