How many Monorail glitches have you experienced so far?

I voted 3(well so far), freezing up, can't store the heights building(even though I had no issues/glitches with storing them), and the minus count job one, if they can't fix them all for some time then the most time consuming will be Apu's 12hr task some 304 times, I don't even want to work out how long it will take lol :)
