Hi! I tested this out on my end and it seems to be working fine as far as I can tell. Have you checked the walkthrough guide for the positions?
If you can't find them after checking the guide, a few questions to help troubleshoot:
- What operating system are you using?
- Do you have any recording software that you use while playing such as Bandicam or OBS?
- Do you play with keyboard primarily or mouse primarily?
- If you press the tab button on the keyboard, does it allow you to highlight the hidden items?
- Did you get the scene earlier in the game where you search for Clive? If so, were you able to find him successfully?
