Bug while using the Eye?

Are any other people experiencing that the Eye sometimes doesn't work?

I have placed the Eye as a pickup, and on some nearby tiles I have ghost blocks, and ghost passages. But for some reason the ghost blocks and passage doesn't work when I test the level....

What to do?

The Ghost Eye doesn't activate immediately, but only after you've changed rooms. If you need to activate it immediately in the same room you pick it up, you could use a Shift to an identical room.

Thankyou!
Helped a lot
