@Liam Actually I found this before any other dupes showed up, did a search when 0.14.0 came out and this was the only one I found. So I believe the others are duplicates if this was the first one to my knowledge.
@Connor Seems to be the case, I wonder if it's because the game encounters an error when trying to start a multiplayer (LAN) server on the device?
Can confirm on iPhone 5S, iOS 9.2.1; seems to happen mostly with worlds larger than a few megabytes (doesn't happen with those around 4-5 MB, but always with those that are 10+ MB). Also, after first try/crash, worlds generally can be loaded on the second attempt.
I beg to differ, my device has crashed upon loading a world with no carpets or paths whatsoever.
