Hello guys,

I just upgraded to 4.7 and everything looked nice, until I tried to launch my game. It now throws errors/warnings that I haven’t experienced before. It’s basically the same sort of text again and again and looks like the following:

LogPlayLevel: UnrealBuildTool: C:\Users\\Documents\Unreal Projects\MyGame\Source\MyGame\Public\Actors\Ship\MGShipPawn.h(17,1) :  error: unknown escape sequence '\A' [-Werror]

LogPlayLevel: UnrealBuildTool:         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
LogPlayLevel: UnrealBuildTool:         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

And in the very end I get the following:

-----------
.....
LogPlayLevel: UnrealBuildTool: 5 warnings and 2 errors generated.
....
-----------
......
LogPlayLevel: BUILD FAILED
PackagingResults:Error: Error Launch failed! Invalid Arguments

When trying to launch a sample project, it works though :frowning:
Any ideas what I did wrong? Do I have to change anything?
Thanks in advance :slight_smile:

Best regards,

Okay I found the solution already myself (finally, tried reinstalling and verifying a gazillion times):
The RPC Calls weren’t declared correctly, I did adjust them as explained here : Forum Thread
The Errors were quite misleading though …
I hope this helps somebody :slight_smile:
Have a nice day!
