Loading a world last saved in 17w50a in 18w01a
Windows 10 Home x64 - 16GB RAM - 2TB HDD - i7-6700k CPU - Nvidia GeForce GTX 970
When I try to load my saved worlds from 17w50a the game crashes.
Some worlds will load for example my world called 'Velus', but the main world that I have spent a considerable amount of time on 'World Of Rick Riordan' will not load and I get a game crash screen.
I have so far tried emptying my inventory & stopping any command blocks from running, as suggested by community members. But this hasn't worked.
I have included 2 screenshots and the crash report.
