Just throwing this out for anyone else who has had the problem. It has been mentioned in the 4.11 release thread but not much around the forums.
Hot Reload is broken if you use a custom AWorldSettings class. Haven’t found a temporary fix for it yet but if I do I’ll post or link it ere. Epic said the fix will be available soon, can’t find any fix on github or in Unreal Tournament build. The crash occurs in LevelTick.cpp when using “AWorldSettings* Info;” to adjust and get delta times etc.
