Bad NullPointerException bug while flying Davincis Vessels Airships #1

Closed ubergarm closed 3 years ago

ubergarm commented 4 years ago

This is a rare bug, but I've seen or heard of it now 4 times that seems maybe like a mod interoperability issue between Davincis Vessels and Topography. Or at least I've only seen it while flying on an airship.

java.lang.NullPointerException: Exception in server tick loop at 

com.bloodnbonesgaming.topography.world.generator.SkyIslandGeneratorV2.populateStructures(SkyIslandGeneratorV2.java:447)

I have opened a ticket w/ Topography folks here: https://bitbucket.org/bloodnbonesgaming/topography/issues/23/nullpointerexception-in-server-tick-loop

The only work around that I know of is to manually edit your playerdata file and change your pos x y z to somewhere else and then abandon that airship! (I've had it glitch me again if I tried to remount the airship, or if airship disappeared even going into that area glitched me again).

For example, your player data can be found under your instance folder in your saved world's playerdata/ directory e.g.

Sky Magic Islands/saves/world/playerdata/00000000-0000-0000-0000-000000001337.dat

Make sure the uuid is for the bugged player, and then open it using NBTExplorer and update your character's pos.x pos.y and pos.z to place them safely back to a known location e.g. x=20, x=85, x=10 or so which is near the waystone on HQ island.

Bummer!

There is a chance this was fixed here: https://bitbucket.org/bloodnbonesgaming/topography/commits/ca319b4b9b59207d017a063d69f1ac35b388e6d3#Lsrc/main/java/com/bloodnbonesgaming/topography/world/generator/SkyIslandGeneratorV2.javaT449

I'll update to latest release of Topography mod and do a little testing!

Just updated modpack to v1.0.0 which includes latest Topography-1.12.2-1.14.4.jar so hopefully this issues goes away!
