So whenever a world on Mobile is edited/created, it crashes after 4 seconds of gameplay. This is a glitch ive dealt with before, but this what slightly different than to the other one. If a world with all the same things as the others was created before the update on the 25th of may, it was fine. As a beta tester, I also want to point out that there is one glitch that is still popping up sometimes. It's where the head of the player clips through any block of there isn't one under it. Hope this helps
