So this issue started yesterday after updating , I updated both IOS and minecraft yesterday so I can’t isolate the variable .

this log issue appears when I select my world : “[Structure][error]-[igsaw Structurell couldn't be constructed, no pool named minecraft:trial_chambers/chamber/end”

and later on during gameplay the  game crashes randomly , but it looks like it happens more often when am with my herd .

I tried : 

• closing all apps
• restarting my iPad
• reinstalling minecraft 
• turning off ad-block
• turning off wifi 
• playing while charging iPad

I did see 2 similar issues (179139 , 173682 ) however the issue isn’t solved by turning off ad-block only
