Remove SS_NO_TICK_CHECK (#57800)

## About The Pull Request
This is a whopper, will need @MrStonedOne to review.
In theory this flag shouldn't be needed and my own testing didn't find any issues, but I'd feel better with a lengthy test merge.

## Why It's Good For The Game
Might make nightshift subsystem lag less, MC loop has less stuff to check.
