Tamed dog with dyed collar causes BDS to crash when teleporting to nether

I was playing on my favorite BDS server (1.10).

I ordered my tamed dog (with orange collar) (tamed on 1.8) to stand up and follow me. I wanted my dog to go to the nether because I built a new base thousands blocks away and I built speedslide (ice track) between the newer base and the old headquarter. Then, when it is touching the portal, server crashed.

Highlight:

1. Dog was tamed before 1.10

2. Collar was dyed to orange

3. Dog was passing through nether portal

4. Dog was shaking water before it happened

Media:

1. Just right after the crash (might be useless, I think)

2. Reperforming the crash. (2~4)
