Event: Destructible within region dies

Event: Destructible within region dies

How can I make that event working? Even when a destructible in a specific region dies, the trigger does not run. There is a tip in the window, that only first 64 destructibles are monitored to death,... But the window is too small and I can read further. Could some help me?
I have about 150 doodads which should be used in the trigger. I tried to make more smaller regions, but it still does not work.

this will take much longer, but you could make the event set to each specific doodad... I don't have my editor running right now, I'll add more once I figure it out.

Yes, but I am creating those doodads via trigger. And there is about 500 doodads.

This will even not be needed, if would be possible to:
make a doodad with ability or unit that could be harvested.

And how does that tip read?

You are going to need to make more regions. No more then 64 destructables per region if you are going to be monitoring 500 total doodads.
