After Unreal Engine 4.13 release, I immediately downloaded and switched my app over to the new engine to make use of the new spline addition in blueprint actors. It worked on my android tablet, but once I released the new update for my Android game I started getting complaints that the game was crashing on launch. After doing some research I believe this is the problem, https://answers.unrealengine.com/questions/482999/unreal-engine-413-opengl-es31.html On the question answer an Unreal Engine employee said that the bug was fixed in Unreal Engine 4.13.1 which he said would hopefully release next week. This answer was posted on September 6th, it is now the 18th. I would like to know the release for the Unreal Engine 4.13.1 bug fix update as soon as possible, the crashing on launch bug has been causing my game to get an onslaught of negative reviews and I want to fix this as soon as possible or at least know a date for the bug fix update.
