Loading existing world on 1.12

[Jameh]

I tried to load my existing world (created in 1.11 I think), on the new 1.12.0-pre.1 version of the game and got the following crash:

I tried to load the world again, to check if it was a first-time load issue, but it keeps crashing with the same error. I can provide the save if needed, but it's 900MB, so would rather not have to upload it if I don't need to

[Tyron]

Thank its gonna be fixed in pre.2, until then, disabling dynamic shadows should prevent the crash
