I’ve just changed the message of the day to describe the workaround for the eating bug in 1.12. This is the first real life test of MOTD so I am quite excited :-) Should download to the phones within several hours. The message says (on the first line) that you should split food stack into single items to be able to eat it.
It feels almost like running a radio station :-D
Btw. the bug is already fixed and eating will be back to normal in 1.13.
