🔔🚨This is an emergency broadcast🚨🔔

Unfortunately a bout of sudden food poisoning has got in the way of our latest recording session. Everyone's safe (now) but as you may have noticed, we're missing an episode.

We've now got a new date in the diary but the podcast won't be back for two weeks - sorry about that everyone!

SO in this episode, A Problem Squared presents...

🧙‍♀️ The first EVER episode of bonus podcast I'm A Wizard.

🪄A latter and very silly episode of I'm A Wizard.

We HOPE this is a good solution to our emergency problem, but only you, the listener, can give us that ding.

And if you'd like to hear more from the Wizards, you can join up on Patreon and give as little or as much as you like.

Thanks everyone!
