I'm just a game player like you, so I don't speak for the devs.
That being said, the changes from the devs are coming fast and furious. The current build that they have out is 1115.7. Personally, I don't believe that it would be in their best interest to start investigating something from a previous build, when they are spending some many hours working on creating even newer builds.
I would highly recommend that you upgrade your game to the most current build (1115.7) and then try your scenario using that. If the problem still persists, then you know that the problem hasn't already been addressed, and it needs to be fixed. Surely you can understand the logic in testing with the most current build, right?
I'll be glad to help you with FURTHER testing, but please do your initial testing with the newest build first, okay?
It is a problem playing in the ....5.7 update for sure....
