Frogs clip through floors and suffocate after jumping when near trapdoors.

Previous bug reports involved frogs falling though the floor when jumping near a door, however there is still an issue where frogs do so (and suffocate) near trapdoors.

• Steps to reproduce the issue: Set up a corridor lined with trapdoors and spawn several frogs in the area (image attached for the setup I used)

• Expected result: Frogs understand the concept of solids and land on the ground below them.

• Actual result: Sometimes, after a frog jumps, it will fall through one block of the floor, get stuck, and suffocate.
