Hello!

As you may know, when pasting a schematic that was made in 1.12 and contains banners into a world in 1.13 or higher, the colors on the banners get messed up.
To solve this problem, my idea was to update all my old creations' schematics from 1.12 or earlier to 1.13.2 or 1.14.3.



This would create following advantages:

• no more messed up banners
• I could replace all red netherbrick textured brick stairs and slabs with proper red netherbrick stairs and slabs

And following disadvantages:

• none of my schematics could be pasted in 1.12 or lower anymore
  
• when updating all schematics to 1.14 there may occur errors when pasting them in a lower version than 1.14 (for example 1.13) because some blocks existing in 1.14 do not exist in 1.13 and therefore won't get pasted

So, my question for you is: What do you think makes the most sense or would be the most convenient for you?
I would appreciate it if you told me the reasons or way of thinking you based your decision on.

Have a nice day!
