I cannot say that error looks familiar. What version of FMOD are you using? Have you tried re-importing the FMOD-UE4 integration to make sure nothing is missing? ---

Hi Cameron, re-importing the integration worked! Thanks for the help! ---

Hi again! Unfortunately, this issue keeps coming back. As a workaround, I have to close the Unreal-editor, rebuild the project in Visual Studio and after that open the Unreal-editor again and package the project. This takes a lot of time. FMOD Studio: 1.10.05 UE4 Integration: 4.20.3 Thanks in advance! ---

This should only occur when the integration source code is changed. How often does this occur? Does it normally happen after something specific? Can you test this in a new/empty project to see if it still occurs? ---

Unfortunately, I don’t have time for that at the moment. It seems to occur in conjunction with “Hot Reload” if I have both Visual Studio and Unreal open at the same time and have compiled my project. As the error says it’s something with Hot Reload: > [@CamperDude3000](#): > > LogWindows: Error: Trying to recreate class ‘AFMODAmbientSound’ outside of hot reload! Those days I only work in Unreal (i.e. Visual Studio is closed and no compiling of code) it seems to work to package the project at any time.
