Hot reloading only works once

Hi,
I am using version 4.7.4 Ubuntu 14.04 LTS 64bit and KDevelop.
How to reproduce:
Create a basic c++ project and add some code. The code is compiled and Hot Reloading works!
Import the project into KDevelop using the cmake file.
UE4Editor now realizes the c++project and offers opening the source code using KDevelop. This works fine!
Now add some lines of code using KDevelop and within UE4Editor hit the compile button.
The code’s compiling but not reloaded.

i m having similar issues with hotreloading in VS2013. Sometimes it works sometimes it doesn’t. The other day I spent almost an hour trying to figure out what’s wrong with my class and why my blueprintcallable functions were not visible. Turned out that hotloading failed and the project had to be restarted. It’s happening again now. Like you said - it’s starts off OK - showing “Hot Reload” message, then eventually it stops completely.
