Strange world of Torque

I made a cage. No errors in Hammer and no errors in map2dif.
But when i lighted the cage in Torque the engine crashed everytime.
Fine, i took the cage three times in one map file (later of corse dif) and relighted the scene in Torque - no crash -
but i was a bit stocky and so i decided to make some detail bruches. But with the detail bruches map2dif tells me: "too many points"

so two questions:
-first, why doesn't Torque light the single cage, why the file with tree times the same cage ?

-second, the error in map2dif "too many points" why does it appear and want can i do to correct the object in Hammer?

thx
