My son just purchased a world (City Life 2 by PixelHeads) with Minecraft coins. When he starts the world, a dialogue box shows that it's loading resource packs, the writing goes away for a bit, then it says it's generating world. Then Minecraft crashes. All other worlds load without issue. Any help is appreciated because my son spent his hard earned money for this.

We are running Minecraft Pocket Edition v1.14.60 on a 4th gen iPad iOS v10.3.3

Thank you
