java.lang.NullPointerException: Ticking entity at electroblob.wizardry.spell.Freeze.cast

Open OfficialStamper opened this issue 5 years ago • 5 comments

Minecraft version: 1.12.2 Wizardry version: 4.1.2 [Electroblob's Wizardry - 4.1.2 - MC 1.12.2.jar] Environment: Server

Issue details: The attached crash report appears in the server log. It does NOT crash the server and is thus not a critical error.

I believe this is caused by a mob farm that is using CC Turtles to do the killing. I have been unable to identify other activity on the server that could be causing the error.

Other mods involved: Possibly ComputerCraft (as described above).

Ok, so it generates a crash report but nothing happens in-game? Could you try getting a CC turtle to kill an evil wizard, and see whether anything weird happens (no drops, or the wizard disappears, or something). Also check the server log to confirm that this is indeed what causes the error message.

I will see if there's anything I can do to get rid of the error message.

The crash was copy/pasted from the server log, there was no other messages at the same time that could have contributed to the error.

Can you give me a clue as to how I can spawn in an evil wizard please? Then I will pause the server from players and perform your test. Cheers

Just noticed this went unanswered. You can spawn in an evil wizard with the spawn egg (under the miscellaneous tab) or with /summon, just like any other mob.

Hi Electroblob77, I have the same issue but crashed on my servers. The server seem crash whenever the wizard (or evil one) casting spell on nothing while industrial foregoing mob crusher can't one hit kill them.

This is such an old issue that I missed it, sorry. Something is causing the player's connection field to be null, the industrial foregoing mob crusher may involve a fake player but I don't know, and it still shouldn't do this.
