App crash when hiding ad the second time (Admob)

Holonist

Hi,

I would like to give players the ability to show/hide ads for a little bonus.

In my app, currently an ad is loaded and shown on start.

When you click the button, the ad hides. As intended
When you click the button again, the ad (or a new one, not sure) displays. As intended
When you click the button once again, my app crashes. (should simply hide again...)

simplified code in my button click listener:

--ad initialization ad = Ads.new("admob") -- ...   ad:showAd("banner", unitID) showAds = true   --this goes inside my button:onclick() if showAds == true then showAds = false   if ad then ad:hideAd("banner") end else showAds = true   if ad then ad:showAd("banner") end end

I'm an idiot.
The crash was not because of ads.
It was because of a sprite that I remove too, but then forgot to add again on the next button click.
