[MC-93808] crash on approach to blaze spawner

In nether, cheats enabled (have only used keepInv, enchant command, and tp on this world), approaching a blaze spawner in a fortress. Just as I was rounding the corner to attack the blazes, the game crashed. I tried relaunching and it crashed before loading completely. Subsequent attempts behaved the same way. So now I can't launch that world at all it seems. :-/ Crash log file attached.

I created a new world with same parameters as before, worked my way through the game to the nether again, and again the world crashed when I started going after the blazes at a fortress. There must be something about the fortresses (blazes?) fouling it up each time.

Please provide the world type, seed of the world and the coordinates of the crash.

Richard Leach 2015-12-04T19:51:26Z

Having a similar issue. Seems to be the small fireballs causing it. To recreate find a blaze and lets it shoot you or other mobs. Added my crash report.

kumasasa 2015-12-04T19:59:29Z

@unknown, this is MC-93655

marcono1234 2015-12-07T21:24:03Z

Could someone please remove the server crash report as that is MC-93655
@unknown you can use programs like MCEdit Unified to remove the problematic fireball

And could you eventually add the world as a zip file?

Blaze Spawners seems ok.

Marcono1234, I can't seem to compress the folder down to the 10 MB max file attachment size for this forum.

Jeremy Jameson 2015-12-07T23:03:49Z

Kumasasa, it was a customized world but the only parameter I changed from defaults was increasing the dungeon counter to 100. The seed was random (left blank). Unfortunately, I did not note coordinates as I was busily exploring the fortress with the debug info turned off and have no way of getting back onto the world to check (because it never loads).

Walter van den Berg 2015-12-08T14:11:18Z

If only my world was created in the snapshot I'd be able to confirm. Dungeon count at 100 and getting the crash, though.

Edit: @Jeremy Jameson You can use NBT Explorer to move yourself to a safer location.

Marcono1234, Walter van den Berg:

While I appreciate your suggestions to use third-party tools as workarounds to get the worlds to launch again, I don't much see the point in doing it. It's not that I can't stand to let go of those worlds and start a new one (I already have). It's that I'm not sure what good going into the nether for blaze rods will do anymore if every time I encounter blazes it corrupts the world so it no longer launches.

Jeremy Jameson 2015-12-08T16:37:08Z

I just got the same problem in a third world (this time non-customized - so default dungeon count) - but it didn't crash right away. The blazes shot several fireballs before the game eventually crashed.

marcono1234 2015-12-08T16:43:49Z

Was it the same crash or was it MC-93655 this time? Also you might be able to attach the world now if it happened in a new world

Jeremy Jameson 2015-12-08T17:02:10Z

Here's the latest world I played on (non-customized; just enabled cheats and used creative mode to accelerate my way to a nether fortress) which crashed after a while of battling a bunch of blazes.

Jeremy Jameson 2015-12-08T17:05:08Z

Also, here's the crash report for the most recent.

marcono1234 2015-12-10T16:03:18Z

The crash report you just attached is actually MC-93655, can you still reproduce the crash that is included in the description and also in the older crash report?

Mat Cooke 2016-10-24T09:20:44Z

Just experienced this crash on MCPE 0.16.0 (latest stable)

I have built a room around a blaze spawner and have a window with which I attack blazes through with a sword - The rods fall onto hoppers that lead to a chest.

After about 3 seconds of attack; the game crashes
