Game freezes every time during world gen when there are Locks, JustEnoughResources and Advent of Ascension mods installed. Removing any of them removes bug, so for example Locks + JER works and Locks + AoA works but all three together not, also JER + AoA without Locks works.

JustEnoughItems without JER always works well.

Crash-reports always says it's Ticking player error.
