You should never mix autonomous movement and set move route in the same event because they will Oberseite each other - and there is no need for that because you can use regular sound commands, no need to place that inside a move route.
That said, nothing in this event could cause this behaviour, the cause has to be somewhere else. That is why I assumed it comes from the (known to have problems) pirated version.
Other possibilities:
An added script?
Or still some of the defects of the pirated default scripts? You'll have to exchange them from a new project from the legal Version to be sure, problem is that to translate the engine the pirates had to modify the script editor as well, and that is not automatically exchanged when using the legal Version.
