I need some help with some video game mechanics in my new game

[ZainreFang]

Alright, check this out. I'm making a game. This game happens to be the biggest game i'm making in my life. I've added tons of things, and my mind is a bit burned out, so I need you guys' help on this.

-Vertical Moving Platforms
For the most part, these work! All I did was copy the programming for the X moving platforms and change X to Y.

However, every so often, when you land on a Vertical Moving Platform while it's moving upward, it won't work. You fall through it. It doesn't happen TOO often, but if it happens at the wrong time, it could cause some frustration on the player's part. What do I need to do to alleviate this issue? Remember when I said I copied the Horizontal Moving Platform code to make the Vertical Moving Platform Code? This glitch doesn't happen with Horizontal ones. So, help me out there. By the way, the moving platforms run on FastLoops, no Path Movements involved. Make the solution as simple as possible. I don't want to create new objects and spread values to create and position them to each moving platform yadayadayada... I would like it to be ASAP! (As Simple As Possible, in this case!). I'm in the "adding mechanics" phase of making the game and I want the "making levels" part to be way easier.

-Falling Spikes
I want some Spikes that fall when you get near them. I want them to fall independently of each other, so if you walk towards one, that one falls, but not all the other ones. I have some -20 < x (collider) < 20 then set gravity to 50 stuff but it doesn't work well and they all fall at the same time. Btw the Spikes are set to MMF2 Platform Engine, and the Main Character uses that amazing Platform Movement Object. So help me there too. I'd rather use some position math than making a huge detector block for each spike, so keep that in mind.

Tell me what I should elaborate on if you need more info.

Falling Spikes resolved, Vertical Moving Platforms still unresolved.
