Long reflection probe build times?

After updating to 5.1.3f1 we noticed that some scenes are getting stuck for almost a minute while building. The line reads Reflection Probes (1/3) and never goes to 2 or 3. Just sits at one. Ours is a simple Android game so I turned off every reflection probe in the project. We've never seen this before and it's tripling our build times.

Any one seeing this? Anyone know why or how to make this stop? We don't need reflection probes.

Also, the scene(s) that gets stuck for a minute changes. Like, it's not always scene 3 that is slow. Every time I build it's different.

 

Yes, I am having the same issue.

 

Me too..
