Issuing Unit commands on a different thread returns false

[vyo]

When calling a Unit command like someUnit.gather(mineralSpot) from a different thread than the main thread consistently returns false;
calling on the main thread consistently returns true, all else being equal.

Any ideas why that might be? Is that a BWAPI thing?

Update:

Seems to have been a programming error on my part, I suspect an uncaught exception sometime during the onFrame event.

Update 2:

That was premature; still investigating.

This is because BWAPI is not designt for multithreating you can only call commands while in you onFrame() methode so try to do it without threads or use a flag if u are in your onFrame() methode
