Background story:
I've logged into my current superflat world to do some testings and I noticed that my world (that was generated in an older version of the game) would not generate the chunks beyond the one I've already generated before.
Worlds that are not affected:
Worlds generated in 20w21a works perfectly (they generate chunks normally)
Normal worlds generate chunks normally even after being converted
How to reproduce the bug:
Generate a simple superflat world in 20w20b (or older)
Switch to 20w21a
Convert your world to the current version of the game (20w21a)
The game won't generate past the chunks you've generated in the older version.
Screenshots attached (I've put the wooden planks myself to see if I was able to place blocks in those chunks)

Please check if you can still reproduce this issue when upgrading a 1.15.2 superflat world to 1.16-pre2 or later.
Can still reproduce using the following steps:
1. Create new superflat world with the default preset, creative mode, generate structures off, in 1.15.2.
2. Open the world in 1.16-pre2 and fly to unexplored chunks
3. Observe chunks generating empty
Hello,
The bug is still present in both pre2 and pre3 versions, every superflat world created before 20w21a will be affected when being converted.
Cannot reproduce in Pre-release 3 using Marcono's instructions - please test it by upgrading a 1.15.2 superflat world to 1.16 Pre-release 3 - other 1.16 snapshots do not count.
I sucessfully managed to reproduce the bug twice. With or without generating structures. I also tried in 1.15.2 to pre-release 3 the first time.

We do not have enough information to find the cause of this issue.
Please add the launcher log using these instructions to this ticket - please copy the log after the world was opened in 1.16 Pre-release 3 and the chunk error has occurred.

Attached launcher log of me opening a freshly created 1.15.2 superflat with structures disabled in 1.16-pre4, flying to the edge of existing chunks, placing some blocks where chunks should have generated, save & quit to title, and rejoining the world to make sure the newly placed blocks are still there.
