Crash after signing into Google Play Game Services

Sorry for all of the posts, I thought it would be better to keep them all separate.

If I do a new install of my app on my phone and open it for the first time, the Google Play Games pop-up will show and ask me to select an account to sign-in to. After signing in, the app crashes. But then I'm able to open the app a second time and have it all work no problem.

Is anyone else experiencing this? Is there a fix for it?

As the Google Play Game Services Objects are purchased separately from the Android Exporter and Fusion, how will updates to these objects be done?

I just did a bit of playing around with the settings on the GPG Connector object such as: checking/unchecking Automatically Login at Start, Log In with UI Box, Log In with default account. Building with beta 285.2k These are the results I got for each scenario:

[ ] Automatically Login at Start
Start of Frame: Log In with default account
Result: Instant crash

[ ] Automatically Login at Start
Start of Frame: Log In with UI Box
Result: UI Box comes up, Crash after logging in. App runs fine after re-opening. Viewing leaderboard and then closing it causes crash.

[ ] Automatically Login at Start
Start of Frame: (nothing)
Result: No login to GPGS, pressing button to open leaderboard does nothing

[x] Automatically Login at Start
Start of Frame: Log In with default account
Result: Instant crash

[x] Automatically Login at Start
Start of Frame: Log In with UI Box
Result: UI Box comes up, after selecting my e-mail it prompts me to Create a gamer ID (Even though I'm already using this e-mail on GPGS), app crashes after signing in. App runs fine after re-opening. Viewing leaderboard and then closing it causes crash.

[x] Automatically Login at Start
Start of Frame: (nothing)
Result: UI Box comes up, Crash after logging in. App runs fine after re-opening. Viewing leaderboard and then closing it causes crash.

I haven't tired it as a beta version, so I've uploaded one last night and just tried it out now. It doesn't make any difference. Still crashes after logging in, and after exiting the leaderboard. My setup isn't really any different than the Test Play Games example, and it used to work just fine without crashing.

This is the apk that's having the problems:

Yes, The whole process of setting it up in the Google Play Developer Console under Game Services, getting the id number, linking the app, getting the SHA from the keystore file, setting up achievements and a leaderbaord, etc. I had previously completed all of those steps. An earlier version of my app has been live on the Google Play Store for the past few months, and it runs GPGS sign in, achievements, and leaderboard perfectly fine without any problems.

I'm not sure where the problem lies, weather it's the exporter, the GPGS objects, my own settings, or something on Google's side. I'm still looking for ways to get it to not crash. I've noticed that viewing the leaderboard then exiting from the title screen causes a crash, but doing the same thing on the game over screen doesn't.

The new version of the app I'm working on is not on the Play Store yet, but is uploaded as a beta. I don't want to publish it live if it crashes. The older version is there and works perfectly fine.
