image one
Just did update, ran editor and the above images show whats happened to my tilemaps in the editor, building though results are as expected in image 3. Tilemaps can be edited correctly with correct tiles being added and removed. Restarting editor, deleting and re-applying tilemaps does not fix problem
Using Latest Nvidia drivers, Windows 10 with all latest updates.
Ouch, seems like a bug related to the UV-flip changes in 1.2.94, so sorry for this. Fixing this is highest priority, thanks for reporting!
As a temporary workaround, you should be able to download the previous version, 1.2.93;
OK, cheers
I have updated my previous reply with links to the previous version.
Thanks for providing this workaround! I had as well a decent oops moment as I noticed that all my levels were messed up 
Quick update; we have located the error and are planning to release a fix today.
Thanks even that was quick
We just released a new stable, 1.2.95, that includes the hot fix for tilemap rendering in the editor.
