Thanks a lot Rob, as well to the rest in this thread! Really great help.
Now can finally put this to rest whilst in the past I used to put removeScene just about anywhere I thought was ok.
Tried it and the game plays smoothly on my ‘Retry’ option as well as jumping from one scene to another.
@Rob,
I am about to update my thread on my build timeouts issues, this time with a complete console log. Unfortunately I am still having that issue. Hopefully you guys can spot the reasons. I need to come up with a playable prototype APK soon at CoronaDefold jam hopefully but not with this issue
