For reference, this is the entity culling mod https://www.curseforge.com/minecraft/mc-mods/entity-culling (can confirm I have this issue too)

I have the same issue with the same mod mentioned above. My only fix is to get rid of or disable the mod.

The config of Entity Culling can be updated to resolve.

1.12.2 Instructions:

Open \.minecraft\config\entityculling.cfg with a text editor and look for "skipHiddenTileEntityRenderingBlacklist"
Should look like this by default:

S:skipHiddenTileEntityRenderingBlacklist <
    enderio:tile_travel_anchor
>

Add "fairylights" like this:

S:skipHiddenTileEntityRenderingBlacklist <
    enderio:tile_travel_anchor
    fairylights:fastener
>

1.16.5 Instructions:

Open \.minecraft\config\entity_culling-client.toml with a text editor and look for "skipHiddenTileEntityRenderingBlacklist"
Should look like this by default:

#Tile entities which will always be rendered. (Format: 'modid:tile_entity_name')
skipHiddenTileEntityRenderingBlacklist = []

Add "fairylights" like this:

#Tile entities which will always be rendered. (Format: 'modid:tile_entity_name')
skipHiddenTileEntityRenderingBlacklist = ['fairylights:fastener']
