Hi @mator, thanks for raising the issue. The http requests failed, probably the server is overloaded hence the timeout, so Cassowary cannot do much more than exit what it's doing. However the panic is not pretty or user-friendly, I will make a releaser later today to more gracefully handle this error

Fixed in v0.9.1
