I’ve experienced an issue where certain Radicals just simply do not display. It is always the same Radicals, I’ve noticed, and it was an issue about a year ago and suddenly it’s reared it’s ugly head again.
Level 1: Gun, Leaf, Stick
Level 3: Hat, Triceratops (Hat is by far the biggest offender)
Level 4: Beggar, Horns, Spikes
Level 5: Kick, Viking, Water Slide
Level 8: Cloak, Hills
As a note, this happens to me on multiple laptops and browsers too (iexplorer and chrome). Tasuketekure!
