Bullets not moving when touching solid

Hey. I'm trying to make some falling blocks with the platform behaviour, but they don't work if they're touching a solid at the side (I've attached a GIF). I've tried using the bullet behavior instead, but the same thing happens.

I've cut the collision box of the block off a pixel at each side n' that works, but I'd rather have the collision be the size of the whole block.

Any idea what's going on here? Thanks for the help.

It would help to know what event/conditions you are using..

Whoops!

Here's how I have it set up

Well you are disabling bullet behaviour when overlapping ground and the one on the left is overlapping the ground..

Jaysis! that fixed it. I need a good facepalming! Haha!

I assumed it wouldn't affect it 'cause they weren't actually overlapping. But that did the job. Thanks.
