1.15.2-1.12.13
1.16.4-1.13.4
Starlight links will sometimes completely break when going through multiple lenses into air. This happens when the chunk they're in is unloaded, or has a chunk ticket of 32 or above. The easiest way to reproduce this is to go to the nether and back.
This breakage is server-side.

I cannot reproduce this anymore in the full release of 1.16.4-1.13.3, so I'll remove it from the list.

Reproduced again in 1.16.4-1.13.4.
