Tekkit Legends Crashing After Loading into World

[GR4R]

Hi,

Had a world which I played in for some time. One day, suddenly it crashed and ever since after re-opening the world, it would crash after being loaded in for a few seconds. I've changed RAM amounts, GPU driver and Java is up to date. Here's the (one of many) crash log:
