Stripcreator's server is flaking out a bunch lately. I'm doing my best to track down the cause so hopefully it'll get resolved soon.
I'm going to use this as an opportunity to optimize Stripcreator a bit. Many users have over a thousand comics and I think those queries are slowing things down during peak times.
Anyway, you might notice some weirdness as I try and fix this stuff. Most likely it'll be in the form of your pull-down comic lists not matching up with reality until I get everything ironed out.
