Game crashes are a priority hence "We are constantly looking into".
The problem with Game crashes such as the one being described in that bug is they aren't 100%.
In order for us to fix a crash we need to first reproduce it, sadly for many crashes they just don't happen that often (There are extreme examples where only x number of users may ever see x crash).
I know i might off topic, but the next update is about to rollout in the next few days, I wanted to have this question get answered a long time ago, Is there ANY possibility that we'll get bigger worlds on consoles than the current (Large) ones we have? Or Infinite like PC in the future by Minecraft Realms or something like that?? Because I don't want to start a new world whenever an update comes out, or all these 20+ would not fit in a large world option Please answer this burning question!!
