The first bug I found was with a mob spawner. I had started a new world with this snapshot and found a Zombie Spawner and I lit the area up so they would stop spawning. But they didnt stop instead of normally spawning on the dungeon floor they spawned in a wall and suffocated.
The next one I found was in the same world and i had made a nether portal and went through it and I turned around at the portal and the portal wasn't lit and the same thing happened when I made a new nether portal in the nether i went through it and the new portal I came out of in the over world wasn't lit.
That's all I found ill post more bug reports if I find any thx for reading.

Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets, and it is easier for you to make multiple tickets than for the mods to separate them.
And please use the search function in the future as all of the issues are reported multiple times.
