I had this for the second time on the lua code in almost all scenes :
The Lua code attached to this scene seems to be corrupted. This is the recovered code.
Don’t know why. Vera developpers will some day fix that I hope.
Anyway here is how to fix when it arrives
Copy the lua code corrupted, paste in that website : https://decode.urih.com/data/ (or any other B64 decoder).
Select B64 as code (yeah, it’s because the lua code is NOT corrupted. It is only B64 coded) and clic ‘decode’.
Then copy back to your vera scene.
Hope that could help.
