In many countries in Europe, gas prices are regulated to change only once per week. Gas lines often happen one day before this change should take place, especially if the announced price is a lot higher than current price. I'm guessing this is what was shown.
Other than that, I can confirm there are no shortages anywhere. Not with gas, not with anything else, although we are now constantly bombarded with news announcing "cold winter" due to Russia closing in their gas pipelines. We'll see what happens.
