[MC-51030] Endermite, phantom, silverfish and baby turtle sinking and suffocating in soul sand

The bug

Endermites, phantom, silverfish and baby turtle walking over or spawned on soul sand suffocate.

Earlier manifestations of this bug are also reported to have affected end frame blocks, but I am no longer able to reproduce that symptom.

Confirmed.

Not sure why the "endermite drowns on soulsand" issue is duplicate to this, but it is true. Also, silverfish suffer the same fate.

Confirmed in 14w17a for endermites and silverfishes that suffocate in soulsand

they suffocate in soulsand in 18a as well. minecart issue was fixed separately as of 17a.

Can we get somebody to update the title then, and then potentially the description as well?

I feel it was a mistake for the minecart bug and the soulsand bug to ever have been merged or marked as duplicate to one another, and bug reports lacking clarity will only be ignored for a longer time. 😞

Can this be fixed just by altering the point in the model which acts as a breathing/seeing point, so that it's not quite so close to the ground?

Done.

They also suffocate on End portal blocks. Separate bug?

Not necessary, updated the summary.

This happens because of the hitboxes of endermite and silverfish and the fact that these blocks are actually slightly shorter than a full block. This is probably why it happens.

Are you still active +iftah gold, or may I be named reporter to keep this issue up to date?

Proposed solution: simply shorten the hitbox of these blocks so that points are not "within the hitbox" until they are lower than the foot position of mobs walking on the blocks.

Changed reporter.

Happ MacDonald 2016-02-05T03:19:16Z

Note: it appears as though in Minecraft 1.8.9 the creatures are harmed both on soul sand and on end portal frames, but that by Snapshot 16w05b only the Soul Sand harms them. End Frames are now safe.

Reasons to fix THIS ancient bug:

Primarily just because it reveals some very strange design issues with the NPC hitbox system that are liable to find other ways of making your life miserable if you only let them. ;P
