Upon entering a world in 18w19a I entered the last time in 18w16a, my player inventory (incl. worn armour or a block on my head like e.g. a carved pumpkin), gamemode, effects as well as my character's position and full rotation in the worldsave gets always reset to one specific point. This solely applies to the player, blocks which were already changed in that world, or e.g. dropped items (which are below the despawn time) persist if you re-enter that world.
If the player had effects applied (in my case it is nightvision) this effect is also persistent, even if you removed it before you logout and reenter the world.
It only seems to happen in:
worldsaves which I entered the last time in 1.12.2.
worldsaves which I entered the last time in 18w16a, but it does, for example, not happen in a world I entered the last time in 18w05 as well as not in another world of 18w01.
(haven't checked 1.11 and 1.10 yet)

Also, I'd like to add that any builds you've made in a world which you entered the last time in 18w16a vanish upon entering that world in 18w19a (as well as 19b, but this is known to Mojang [ProfMobius tweets, just mentioning it for those reading this bugpost and not knowing]); but if you enter in worlds you entered last time in an older 1.13 snapshot version, e.g. 18w01, the builds will still be in there.

@unknown Hello Mr. Q, I'm very happy to see you around 🙂
Thank you very much for the help, I didn't get to test 1.12 worlds (or prior to those) yet, there's just too many bugs in this snapshot version. The setback also happens for me with 1.12.2 worlds, but, oddly, not in worlds I've been last time in 18w05 or 18w01.
Thank you again, have a wonderful week.
This happened to me, except upon switching to 18w19b, my position and inventory remained the same, but world generation was reset, so any changes I made to the world in the older snapshot were basically undone.
@unknown In which MC version did you enter said resetting world for the last time? 18w16a?
If so, Professor Mobius tweetet that the issue of a "wiped" world, if it was entered last time in 16a, is still not fixed! It is solely fixed for worlds prior to 16a.
I already reported it, and it’s all command blocks for me, powered, unpowered, impulse, chain, repeating, every single one of them. (MC-129615)
Just quickly @ Mr Q: No, they are nearly all at spawn, I just conducted a test with a 18w16a loaded world and could reproduce it (I proof-recorded it); interestingly, an ICB that I had saved pickblocked in my hotbar still got his command, whereas allothers (ICB + CCB + RCB, one powered, one not) with the command "say test" were wiped upon loading them in 18w20a.
But this one here seems to be solved.
Confirmed for 18w19a
This also happens from a world created in the latest stable release - 1.12.2 when updating to 18w19a
Inventory and player position are always reset to state during previous loaded version
Steps to reproduce:
Create a world in 1.12.2
Put random blocks in your inventory
Update to 18w19a
Change items in your inventory
Save and quit
Reopen world in 18w19a
Inventory will be reset to the first update
