I found out what was causing this bug in my case. I was running the Windows 10 Minecraft app from my Micro SD card (32 gig). I was doing this because my laptop has limited hard drive space. Game was refusing to save while doing this prompting the message. As soon as I switched the Minecraft app back onto C:\ drive the error stopped and I was able to play normal.
Same here. All salmon are missing their tails.
I just experienced this exact same problem. Any End City I find in my world is completely devoid of Shulkers if rendered in Survival Mode. However, if I discover an End City in Creative, Shulkers everywhere. This of course makes getting Shulker related achievements impossible since you can't use Creative mode if you want to earn achievements in your world. Total drag.
Is there a known good server I can test? So far I see this problem on if.mymcpe.com and KingdomsCraft.tk.
Yes, still a problem in 0.14.3.
I still see this on every server I tried. 0.14.0 Windows 10 Edition Beta.
I just updated to Bedrock Beta 1.11.0.1 Windows 10 and now the Minecraft app crashes immediately at launch. I appear to not be the only one.
