A lot of this stuff is to do with new stuff from the newest update. I know it's confusing so in the future I'll open a thread for every major update. For now I'll split and merge some posts in/out of this thread to categorise them better. Will do this a bit later today.
Just to clarify: Similes/emojis are a part of the newest update from yesterday morning. As is the strange tiled backgrounds.
Unfortunately I had no choice but to update as instructed - it was a prerequisite to getting someone to look into the issue we've been having of a corrupted 'datastore' - like the theme etc. that seems to be happening every 7-10 days.
