Block instances are hidden

A block that was used multiple times throughout my layouts (and another block in my model) suddenly does not display. The command ‘show’ doesn’t work, and enabling all layers neither.

The layer that the block is on, is enabled and the layer on which the block contents are, is also enabled.

Selecting the block in the block manager does show the block instances in the viewport with a ghosted-ish review (pink down below).

Selecting the block shows a preview of the instance in pink, this disappears by clicking anywhere else:

This block’s contents are on layer 'Title":

Layer ‘Title’ is enabled:

CABXAB_STR_V03.3dm_(69_MB)_-_Rhino_8_Educational_-_2026-07-30_22-47-46

How do I get the block (instances) back?

Hi Ludo -

Are you still seeing this issue? If so, please post both the output from the Rhino SystemInfo command and a 3dm file that we can take a look at.
