Just did a conversion each way. Converting from 1.12.2 to 1.13 snapshot left world intact, so hopefully no problem with released version. Did a conversion from 1.13 back to 1.12.2, and world structure was lost, but character still carried his usual load. So problem is only one-way.
Have not tried to convert 1.12 world through intermediate snapshots. Not much help since released version will be after the latest snapshot. What I would like to know is if 1.12 version will still be available once 1.13 is released, or if will be forced to "upgrade" to 1.13. At that point, if world can be converted (with structure intact), or be forced to start new world. Prior to 1.13, version structures were able to be upgraded to next version, although some features would not operate unless world created in new version. With 1.13, the new world generation system has so far made it incompatible with older versions. This is requiring mapping software to be changed to accommodate the new system. If the new system can't convert old structures into the new system, perhaps a "compromise" could be arranged by allowing your character to "carry" a load of items and materials so he doesn't have to start a new world from scratch. I had the impression this occurred during my conversion attempts.
Thanks for interest. When trying to convert from one version to the other, it shows up in red and tells you that data may be corroded. So I'm sure the designers know what's happening. Wish they would tell us if that will be true for released version.
If convert 1.12.2 to latest 1.13 snapshot, the world starts over, losing all houses and boxes, etc. Probably because of the new world generation system. Will this happen with the released 1.13? I do like the fact that 1.13 doesn't have all the crashes that occur with 1.12, but if have to start world all over (for about the 10th time), I may halt playing until things settle down. Presently playing a 1.12 world and a 1.13 snapshot world.
Minecraft worked fine on my Windows 10 system with Edge browser before, using 1.10.2 and the 1.11 46a versions. Got message to update Java 8 update 111 and did so. Now when I start Minecraft, loading is slow, and character movement very slow and jerky. Graphics seem to be fine except for slowness. When I try to quit game, nothing happens. When I press the X button, get message that action not supported by Java. Then select quit program from menu (two choices). Game quits and get list of actions/problems, including statement about possible change to timeline and can't keep up.
Have considered trying to go back to earlier version of Java (update 110?). Don't know how to revert Java back.
New problem surfaced a few days ago on version 6 & 7. Every once in a while (6 or 7 usages) the program goes into very slow mode, taking minutes to load the white bar after selecting a world and hitting 'Go". Continues to be slow, until I reboot the computer.
I also had a problem with my large game. Actually, I was playing at the time it "died". It was working with my 27M game while approaching a Dungeon. However, when I got close to the Dungeon (less than 16 blocks) and tried to activate, it came on, and as it finished loading, bombed off. No changes by me up to that point, except getting closer and game save increased. I did note that the treasure chest contained a gold music disk, a new item for me.
Have now tried version 6, and program works fine again.

Latest snapshot w22c replaces all Mending books with Protection books. Hopefully Mojang can change back books.
