I am more scared about forgetting /c and write annoying non-english sentences in global rather than exhaust my fingers for pressing those heavy buttons and write the two letters.
Yesterday my crew used the chat all day with no issues. I used it too in the evening when suddenly around 22:00 or a little bit later (England time)  I noticed people asking to speak english, and then I noticed the bug. That was the timing, at least for our crew chat.
