radiator-0.3.12 there's a major performance improvement when doing lots of transactions. Basically, it avoids a persistent http connection for network broadcast because it's overkill. If you only run one bot or the bot doesn't do very many transations, you'd never notice the problem. Or, if you do a lot of transactions but the app closes every so often and restarts, this would also mask the issue. To update, just do bundle update.
