Bees Behave Strangely to End Rods

So, as mentioned abode, bees are behaving strangely towards End Rods.

The AI will fly into the End Rod, as though expecting to phase through it. I experienced this glick largely at night/when raining while bees were trying to enter the Nest. Occasionally they'd reproduce this during the day, but this is especially noticeable at night/while raining. I have an assortment of screenshots to share below (with debug screen open).

For reproduction:

1. Put bees in a chamber (about 10x3x10), preferably across a chunk boundary.

2. Place End Rods along walls.

3. Place nest along a wall, with entrance facing outwards.

4. Try to have 10 bees in the chamber.
