Just updated the plugin on a site and immediately Simplified Chinese went missing.
When going into the settings the Chinese flag is still there, but when clicked the plugin gives two options> Taiwan Chinese and HongKong Chinese.
The latter never has been an option, anywhere, ever, so there is some weird stuff going on.
EDIT: actually I saw on the 1,0,1 version also the choice ZH_hk ...
For now I have reverted back to 1.0.1
