Using 4.13.1 on PC and developing for GearVR on Samsung S7.
With 4.13.1 I get many app crashes on level load in app. Multiple different of my apps are crashing, always on “open level” BP. Crash happens randomly in almost 50% of app runs. If first level open works then the whole app works perfect with every following level load, else app crash on first open level BP.
I think 4.13 didn’t have the problem, but have to look into downgrading now.
Best way to go about this is to post bug report on AnswerHub with a test case (preferably) so that Epic can reproduce it easily.
