I have downloaded your 1.12 world and upgraded it to 20w12a. I get spawns of all types.
confirmed for 20w12a
confirmed for 20w11a
Still present in 1.15.2?
Can confirm for 1.15.1
The items are not on ground in 1.15, but the chests are still not there.
For easier reproduction use the same seed: -2181991686956486103
tp 1254 23 1210. Use ender eyes and enter end, then tp to -1512 95 358
Confirmed for 1.15pre2
Confirmed for 1.15pre1
Easiest way to reproduce now, is by using Elytra and open inventory.
Affects 19w42a.
Yes it is getting better. I attached a new crashlog made in 1.14pre1.
Note that it crashes once and then that area is good. (may crash in other areas)
Cannot reproduce.
Remember that the full beacon reaches max 50 blocks down and build limit in the up direction.
After further investigation I have found out that you can replicate this by starting a 1.12.2 world and then directly upgrade to 19w11b.
If you upgrade 1.12.2->1.13.2->19w11b it does not happen.
My world has been upgraded from 1.8 , 1.9 ,1.10 ,1.11,1.12 and now to 19w11b. The rain penetrates blocks that was generated before 19w11b. You can dig a hole in a hill and it will rain. You have to place blocks above you to stop the rain. When you remove them the rain continues.
I tried again in 19w11b and the game still crashes. But this time I get ticking world crash. (New crashlog provided) As a workaround i can restart the game, and try again and the game will not crash in that area. It will still crash if i move towards my base ie.
The game feels in general very laggy (speed of chunkloading, elytra deployment)
I did not use the optimize world option before playing.
I have kinda similar. But upgrading from 1.12.2 to 18w20a. Stuck at: preparing spawn 95%.
Gets a crash log but doesn`t close.
Has been fixed by 24w45a. I am able to reproduce in 24w44a, as per screenshot of the log output. (24w44a.jpg)
