Version: 26.3.461

If there is only 2 blocks of free space above a dungeon teleporter, you take a bit of damage when teleporting back to that teleporter.

For example at X Y Z 659 70 302 on the server.

Bad thing is: if I dont do that there is a propability of falling strough the bottom (Old mojang bug, as they sync the heigh as byte and not as float)

It is fine then, it is not that big of a deal.

I guess you can mark this as wontfix.

After digging around this glitching through bottom bug is the same as when entitys glitch though fences.

Perhaps this is the bug?

Seems like it was fixed in 1.13.

yeah, basicly when the hitboxes already intersect then you will glitch though, thats why I am teleporting the player to high, I reduced the offset from 0.5 to 0.2 so the player should nolonger be inside the top block.
