When attempting to optimise a world created in 1.12.2 into 1.13 the readout indicates 'Failed' before optimising a single chunk. When the world is opened it generates the world as it was brand new, deleting all my builds.
When I try to open the world without optimisation the same thing occurs, I am spawned in my last position, but the world has regenerated to an 'as new' state.
When attempting to Optimise - Game output error reads:
| Error upgrading world java.lang.NullPointerException at bwg.a(SourceFile:138) at bwg.a(SourceFile:81) at bnm.a(SourceFile:107) at bnm.a(SourceFile:822) at acx.o(SourceFile:89) at java.lang.Thread.run(Thread.java:745) |
Complete log of both situations attached.
