This isn't a duplicate of that issue. I did a search, and nothing close to what I am experienced is listed.
I can play all day in 18w45a goto the nether and End and come back to my base and not have my shulkers have an issue.
So how about you read my issue then read the issue you say it is a duplicate of and you will see they are not the same.
It didn't crash the game.
Sorry, got a bit crazy with the snow and no internet, I can confirm chickens "dying as intended". Thanks for the fix.
It is a quick tick pulse on the dispenser... The lava doesn't stay long enough to be knocked back into it. As soon as the dispenser pulses the chicken is dying.
Still an issue in 47b?
