@Minecraftpoweer same, I only ever had it on android

This happens if you tap undo rapidly. Those blocks would disappear if you exit the editor, Load level, or restart the app

Oh and this is a slight teaser.

Ok thanks. @F104Deathtrap

@Caveman999 I've had this happen to me too many times. Now, I save over and over. I start with A1 and when I get to A20 I start overwriting. Usually I go through 30 or 40 saves before I'm done. I still use the "undo" button, but I pretend it's "cheating" and try to avoid it whenever possible.

Ok thanks guys @F104Deathtrap @Minecraftpoweer

Save often, don't overwrite saves and avoid using the undo button.

@Caveman999 probably mobile only problem, Before doing major Changes and stuff save it while it works as a backup and sometimes save it and rename it so that it is a backup

On my ipad@Minecraftpoweer

ik it does that sometimes but i ave never had it while on pc

Yeah,do what Astley said.

Pink is the no texture color, i think
FYI: you can reduce the chance of part doubling if you only press undo when the previous undo is complete

@AndrewGarrison. The pink area was white and then it just went pink.
