No other errors, no. If I manually check it out (or un-tick ‘Read Only’ on the file) each time, it works.
EDIT: I’m also getting these warning messages in the output window of VS2013 when building my game project:
1>LogModuleManager : warning : Found module file …/…/…/Engine/Plugins/Script/ScriptGeneratorPlugin/Binaries/Win64/UnrealHeaderTool-ScriptGeneratorPlugin.dll (API version 2217540), but it was incompatible with the current engine API version (0). This is likely a stale module that must be recompiled.
