I logged in to my world and immediately saw that a building i had made was gone [blocks were invisible and glitchy] and i thought it looked like the Assassins Creed 4 boat glitch a bit.
Also, there were lighting glitches on the whole thing.
What I expected to happen was...:
When i placed a block next to the missing chunk i expected it to update the lighting and block visibility
What actually happened was...:
the first 2 blocks i placed, the lighting glitches did update but the blocks did not, the third block i placed crashed the game
Steps to Reproduce:
1. Load a world with man-placed blocks in it such as a custom town
2. Find a missing chunk with lighting errors
3. Place a block by the missing chunk if the lighting updates it means its working
