when ever i changed speed no matter what when i get pass the 50 floor i clip through i have the fix file as well still clip through

Have you read through the info in the older threads related to clipping?

For instance, are you standing close to a wall, close to a horse, or close to a garage door?

i have and its just a plain elevator going up 100 floors

Ok I'll test to see if I can reproduce. What speed do you have it moving at?

2 quad

Cool, I reproduced the issue once so far. Got dropped around floor 50 while going up at 2x quadratic speed. I'll investigate.

Edit: I determined the root caused and released a fix in v1.2.6. Thanks for reporting!

yes thank you seems to have fixed it awesome!
