Enemies can't jump sometimes

[Fralex]

For a while I've been trying to modify DavidN's fastloop platform movement engine to move multiple enemies at once rather than a single player. I'm doing this by having the two colision sensors( The mask and the detector) jump from enemy to enemy so fast it's as if they're with every enemy at once.
Vertical movement works fine except for jumps. For some reason, enemies can jump if they're standing on platforms, but not obstacle backdrops and obstacle-like objects! What am I doing wrong here?

[Fralex]

I've noticed that the detector does not overlap obstacles, just platforms, if that's any help. Don't know why yet.

Are the obstacles on a different layer?

[Fralex]

Nope, it's only one layer. And they can still stand on the obstacles, they just can't jump.

[Fralex]

Oh! Almost fixed it! By rearranging action order, I've gotten the jumping to work, no matter what the enemy stands on. Now all that's still messed up is the spring. For some reason, enemies won't bounce on it. The detector seems to jiggle now, which is weird... Is that bad?

[nivram]

The detector should not jiggle.

Any ideas as to what I should do?
