AFAIK this is intended. Mobs only suffocate in solid blocks, double slabs are solid, half slabs are not even if they are arranged like this.

Going to add a video later today of how to crash your MCPE. Once I have access to my laptop.

Just downloaded new update and added 0.7.1 to version list.

Never thought about that but it makes sense since water and lava are treated almost the same, besides flow speed, length, and damage...

This comment explains the side-view screenshot of two similar builds causing this glitch and one solution build.

The build on the back left demonstrates why this bug happens, the picture on he back right shows what the game registers when you build your setup, the build in front shows how to fix the problem momentarily.

Noting that the bottom build works and allows the player to easily step up slabs, the game has the code, but it may just be the order it was entered into the source (it checks to see if you can jump before it checks to see if you can step up the slabs)

I am using ipod touch third gen and do not have this problem in 0.5.0. Because mob spawning was slightly nerfed my a max mob count rule the suggested mobs in caves could be a problem. Also, if you are testing this in a cave, note that mobs only spawn more than 24 blocks from the player. Stay in a safe spot above ground and observe a full day night cycle. If mobs still do not spawn then this is a bug.

If I had the power i would confirm, I am using an iPod Touch 3rd Gen and get the same problem. It happenns because programming was added to make the player jump if there is a block, a space, then another block one level higher. In the current version this can be solved by making slab staircases use two slabs on each level.

Im pretty sure the dev team will not debug a modded mcpe considering that is not what they designed the game for. I would send this bug to the developers of the mod apps you are using instead.
(And i do know it is modded because you can't normally use the nether reactor in creative.)
If you can produce this bug on an unmodded MCPE you would probably get better results here.

First picture shows skeleton sitting still and shooting. Second and third pictures show a creeper before and after I walked into its attack radius. Fourth shows a zombie not swimming at me. The creeper pictures also show pigs that have been "stuck" for months

This image shows the pathing lag and a server statement that causes me to think this bug is from internal server lag. Usually cases are not as noticeable and once again only last a fraction of a second.

Image with creeper is before, image with smoke is after.
