I have a problem with bound blood drop.
As soon as I started it nothing unusual happens, but as soon as I switch the modes, minecraft crashes.
I almost lost my world, where I played for 2 weeks!
I hope this bug will be fixed soon.

Thanks to google translate

I hope you follow the issue template, as I can not help you otherwise.

Okay, I can provide you crash-report file and video with that bug.

(When I changed the mode of bound blood drop the world can not start until I remove this drop with the help of third-party software)

Ok, it seems to be a problem in EC compat (incompatible ItemHelpers.updateAutoFill signature). Will look into this soon.
