Issue still occurs with UE 4.20.2 and GA plugin 3.0.2

[the1schwartz]

Thanks, I am looking into it.

[the1schwartz]

I have just released a new version of the Unreal SDK (3.0.3), you need to download the latest version of the Unreal SDK (https://github.com/GameAnalytics/GA-SDK-UNREAL) as well there is also some fixed in the Unreal files as well. Please let me know if this fixes the issue and so I know if I can close this issue or not.

[BonAppetit34]

Fix verified. Described issue can not be observed in GA plugin v3.0.3 anymore. Thanks for the quick response.

Great thanks again for reporting this.
