No worries.
Afaik there arent any adverse effects.
Note however that physics can go through all collision depending on the poll rate (in engine its called sub step), the speed of the object, and the size of the collision.
Essentially, small things fall through a lot.
This is just because the calculations to determine a hit have a really high chance to fail to detect an impact when the check for it occurs only before and after the supposedly impacted object.
For instance,
An ok solution for projectiles is to scale the collision by the velocity so that each frame you check the same amount of distance the item supposedly traveled for possible collisions.
(Should also serve as a test case to understand the above…)
