my temple collapsed

I had a strategy and it collapsed!
I tested it on four rooms, and after receiving the Dynasty Stone, the room didn't disappear!




What happened?

Sorry, my English is bad.

All looks legit:
1) Garisson next to Architect was locked, can't collapse.
2) All other rooms are special (restricted) rooms, they all are 1-time use each (loot the container or activate the device to mark it as used), so had to e destroyed.
3) One room left, because you didn't loot it, i.e. not used. The fact that you have Architect in place means, you never entered his room, which likely indicates, that you didn't visit last 3 rooms that remained untouched.
4) Next run you gonna lose (with chance) Garisson between Architect and lineage stone even if you didn't visit it, unless you lock it again (do not recommend, it gives you nothing), the Architect and lineage support room will remain until their collapse conditions met (visited\used).
