... @cimarronline @EL797 @Anomynous in case if u are interested to check what happen inside (L I N K)
@Ray Aznable Yes, I saw inside, but nothing moves, it just triggers. It's a mystery... And I think the intended (easy) way to trigger it: Spoiler Just put B on the metal block in the doorway. When Z steps next to B (and zaps) it triggers.
