I had a lid crack that allowed it to leak externally. It cracked between the threads, so not enough pressure on the o-ring
Julian sent me a replacement lid
Just be careful that you always keep the threads clear of any media and it's best to use some silicone lube on the o-ring, then just past hand-tight
I did this for a year and a half and a lid still eventually cracked,
but I most likely over-tightened it at some time as I'm famous for making things 'Greg Tight'
