please give more details about the crash like what you were doing

Pierre Killy 2019-03-27T20:53:07Z

I've filled MC-146817 but I'll describe here what I was doing.

First time it happened I was breaking oak wood slabs from bellow with an enchanted diamond axe. I repeated this several times.

I then joined the game and did some other stuff. It all worked. I've broken more oak slabs but more slowly and it worked.

I felt confident, I started to break spruce logs quite fast and it happened again. It might be related to the speed of breaking, or the fact that I broke several things without releasing the action button (my 2 ct)

Thomas DiStefano 2019-03-27T22:16:57Z

I can confirm as well. This is a world ported over to different snapshots since 19w07a, upon breeding (/tp to the villager reveals hearts and leftover bread on the ground, thrown by a separate villager). I can remain in the save for about 10 seconds from load finish to crash. Same entity description (NULL vehicle), except on Arch Linux 5.0.2-zen1-1-zen, Oracle JRE 1.8.0_202.

Max H. Stone 2019-03-28T09:23:21Z

Can confirm this in 19w13a! I was in a village and before each crash I see villagers breeding. After some more crashes in my world was night. I was able to play all night without a crash! In the morning, when the villagers woke up, the game crashed again with "java.lang.NullPointerException: Ticking entity". Another hint for breeding? Switching back to snapshot 19w12b everything is fine and no more crashes with villagers.

Btw: My world is a old 1.13.2 that I upgrade at 19w05a and all following snapshots installed on different PCs with Windows 7 and 10. In the village I set beds, workplaces and a bell.

Marco Selle 2019-03-28T14:42:04Z

It's resolved?

My Villagers just start breeding.. GAME CRASHED (like the log you see at the top)

tried it several times but still crash while they want start breeding

Yes, it seems to be in 1.14 Pre-Release 1 back... Yesterday evening by testing on a old Core i5 (1st gen) computer with Windows 10 64bit and had no crashes. Now on a Core i7 (6th gen) with Windows 7 (64bit) it crashes immediately. According to the coordinates, the villager is a bit outside the village and 17 meters above the ground.
