Scripts are being inconsistent!

Recently finished a new linear infection map called Escape The Station. I constantly get bugs of objects and scripts not spawning/working on even rounds 2, 4, 6 etc. which I have already mentioned on previous posts with previous maps. But, I am now having a new problem with the scripts themselves.

The first section involves using some elevators that I have built. They are set to move 100 units vertically, however on some rounds, they move less than this, and do not line up with the doors at the top (making users get stuck inside). Other rounds they work perfectly. Another issue is also the timing of the doors, they should open when the elevator gets to the destination, but sometimes they take an extra several seconds until they open, even though they are always set to open after 10 seconds of leaving the previous destination. These timing and distance script issues seem to mainly occur on even rounds (like with the other bugs I mentioned above).

Anyone have an idea why this is happening?
