Every time I Play in “Standalone Game”, or “Mobile Preview” I get a crash upon starting which I’ve included as a gist here: [https://gist.github.com/schetle/29ce5aebb0e3b89411c2](https://gist.github.com/schetle/29ce5aebb0e3b89411c2) It works fine in PIE, it also works fine when running -Mac-DebugGame.app ---

Hi schetle, I wasn’t able to reproduce any crash using Standalone Game or Mobile Preview in 10.10.1. Does this happen in a new project as well, or only in your current project? Please and attach crash log for project. > **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)** > > After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline.

Seeing as how every time I tried to attach this upload procedure gives me “No such upload” - I’ve included it as a dropbox link here: [https://dl.dropboxusercontent.com/u/140945/CrashReport-UE4-Ze-pid-30690-77916bbd9b4ba067f17e868364793719.](https://dl.dropboxusercontent.com/u/140945/CrashReport-UE4-Ze-pid-30690-77916bbd9b4ba067f17e868364793719.) In editor log ( magic line, right before dump), it looked like it was being caused on initializer for my Character class. I’ve since changed initializer and don’t get crashes anymore. only things I changed had to do with playing around with default settings on capsule and mesh components, such as simulate physics. I can’t imagine a typo would’ve gotten through compile process, but I’ve seen weirder things. ---

Do you know specifically what you changed in your initializer that stopped crashes from occurring? ---

Hi schetle, Thanks for letting us know that changing initializer fixed your issue. If you continue to experience crashes in Standalone game or Mobile preview please hit “Submit” button on Crash Report pop up window and let us know by updating this thread. ---

My train of thought was that I could default rotation of meshes generically on all of my Character subclasses (Player, NPCs) - as all of their meshes were centered in capsule, and their rotation was off by 90 degrees. I wanted to do this so I didn’t have to change blueprint subclasses if it could be done generically on backend. I had set Mesh component to a negative Z on location, and slightly different rotation on Character initializer. I tried duplicating what I did before, and while it’s a separate issue that my values aren’t sticking when I blueprint off my Character class - it’s not giving me desired error when I Standalone play or Mobile Play. In retrospect, I probably should’ve made a copy of my project that was causing issues and worked on a different version since I wasn’t sure where error was happening. I wasn’t aware of particular crash log that tipped me off to it being initializer, or I would’ve been able to identify it easily. Next time! _shakes fist_ ---

Hah, that’s okay. If you see that crash again, let us know what code caused it if you can. Glad you got it fixed, though!
