Redstone components randomly dissapearing

i have a server at home that i usually play on. and i have a furnace array that uses a 0 tick bamboo farm as fuel. but for some reason there is a spot where the redstone dust just LOVES to vanish for no reason.

(edit: if it helps i added the chunk borders and F3 menu as a screenshot aswell)

What I expected to happen was...:
the components stay where they're placed

What actually happened was...:
some of them randomly vanish

Steps to Reproduce:

i have no clue
