It's weird how a tiny UI rule can stall an entire session. You open the Vaal Temple interface, you've already got a route in mind, and then the game refuses to cooperate because the "Run Temple" button won't light up. If you're farming and watching your stash of PoE 2 Currency , that forced pause feels even worse, because you're not trying to decorate a floorplan—you're trying to play. A lot of people call it a bug the first time they see it, but it's more like an invisible safety latch that doesn't explain itself well.
Why The Button Stays Dead
The idea came in as a deliberate guardrail: the temple needs at least one room "committed" before the run counts as valid. Devs have talked about it as structural integrity, but what it really means in practice is misclick protection. You can't accidentally burn an instance by slamming Start with an empty placement. Sounds fair on paper. In the moment, though, it's brutal, especially when the tiles you rolled are junk and you don't want to lock in a bad branch just to satisfy a checkbox. The UI doesn't give you context, it just nags you to place something and blocks everything else.
The PC Workaround Most People Miss
On PC there's a bypass, and it's the kind of thing you only learn from other players. Hold Ctrl and click "Run Temple." That's it. No extra room forced, no "fine, I'll waste this slot" compromise. It basically tells the game you're doing this on purpose, so it lets you launch the run even if you haven't added anything new this session. Controller users get a more obvious flow: a confirmation prompt that makes the risk clear. Keyboard and mouse players? You just get silence, unless you already know the modifier exists.
Why Players Get So Mad About It
The frustration isn't only the grayed-out button. It's the feeling of being trapped by your own planning. Sometimes you want to preserve a setup you've been building for several runs. Sometimes you're waiting for a specific room to appear, and anything else would mess up your connectors. And there's still no clean reset or undo, so a single forced placement can snowball into a layout you hate. That's why forum posts pop up claiming the instance is broken or the character is cursed—it looks like a hard stop, not a design rule.
Keeping Your Runs Moving
If you're stuck, treat it like a choice: either place a room you're comfortable living with, or use the Ctrl-click override and go now. It's not elegant, but it keeps momentum, especially when you're juggling maps, upgrades, and trade windows. And if you're the type who'd rather smooth out the grind—restock quickly, grab upgrades, and get back in—sites like U4GM are often used by players who want a straightforward way to buy currency or items without turning every session into a spreadsheet.
