Cache Achievement Descriptions crashes on Android

I have a blueprint that successfully calls Connect to Service, and Cache Achievements, but the Cache Achievement Descriptions node crashes. This is when using Play on Android.
The crash is an assert in the UnrealEngine.cpp file checking that a world context object should not be NULL – but it is.

This is built on Windows, with stock 4.7.6 engine, with stock “blank” new project, set up for Android and Play.

D/UE4     ( 2141): [2015.04.23-04.29.59:867][  0]Assertion failed: Assertion failed: Object [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.7\Engine\Source\Runtime\Engine\Private\UnrealEngine.cpp] [Line: 7244]

Here is the blueprint. Note the circled-in-pink area – if I connect that flow from Success so it actually calls the cache-achievement-descriptions function, then this crash happens. It doesn’t happen the way it’s actually wired in the picture.

Hi jwatte,

Do you mind attaching your blueprint screenshot to this thread so I can get a larger view of your setup to attempt a repro of the crash? Also, if you can [locate the crash and attach to this thread][1] that would be very helpful.

Thanks!

Note that this is on Android; the thread you linked to is for Windows/Mac.
The line in the log that describes the crash is exactly the line I copied. (This is from adb logcat)
I can extract a larger subset of the log in the evening today.
Attaching the image as an attachment here. (Btw: The forum sometimes refuses my upload, so I have to link to an external site.)

Ah, I just assumed you were seeing the crash in the editor and not on the device, apologies. If you can include the entire logcat that would be also good. Thank you for your screenshot, I will attempt to repro.

I’m attaching the log file (very slightly redacted where some IDs are replaced with “*”)
Search for “assert” to find the crashy location.

This appears to be the same issue that was addressed in [this pull request][1]. I’ve submitted the fix to our main branch, and it will be included in a future release, likely 4.9.

Could you take a look at the Cache Achievements and Read Leaderboards as well please? someone is already looking at it, but I have the feeling all the query’s to achievements and leaderboards are having problems.

The cache achievements also make my game crash each and every time
