Reminder to never do this kind of thing !
Never call same time the same var name into loops.
Code
<action name="myloadscene">
for(set(i,0), i LT scene.count, inc(i),
loadscene(%1, '', NOPREVIEW|KEEPVIEW|KEEPMOVING, NOBLEND);
);
</action>
<scene name="myscene" onstart="mysceneaction">
...
</scene>
<action name="mysceneaction">
for(set(i,0), i LT hotspot.count, inc(i),
...
);
</action>
