It looks like all command block data is wiped due to a com.google.gson.JsonSyntaxException
, which is visible in the log files:
I even thought to myself to back up my world and boom, all command block data is gone... ;_;
*EDIT:* Whoops, didn't read everything in the description
One of my command blocks (it was a NBT CB containing a command for a 1.13 snapshot) I had in my saved toolbars and placed in a 1.12.2 world kept its command upon loading it, but all others (ICB, CCB and RCB with a simpl3 "say test" command) were wiped.
It's the same things for chain and repeating command block, all of the commands inside disappear when I update my map in 18w20a :/
