IOS 9.3.4 crash supposedly on ipv6 network ?

I’m trying to submit a new update to Apple and it gets rejected,
but I cannot duplicate the issue, even when using NAT64 from my Macbook.

Review claims the app crashes right after combining the last 2 circles,
when using ipv6, and that’s when the app submits a game center score.

Has anyone else noticed any issues like that with Codea?
Like I said I cannot replicate this at all on my ipad air.

Looking at game center code … why do we return 1 by default ?

static int gamecenter_enabled(struct lua_State* L)
{
lua_pushboolean(L, [GameCenterAddon sharedInstance].gameCenterEnabled);

return 1;

}

Oh crap, reviewer was signed out of game center,
and I was still submitting since I had an error …
if gamecenter.enabled then
instead of
if gamecenter.enabled() then

That brings me to another question …

Is it possible to get the highest score from game
centre into lua for the currently logged in player ?

Something like … gamecenter.getScore(id) ?
