Vaal Temp Destroyed but HOW ?

Hello There

I don't have photo of exactly before destroyed my temple but i have it few hours before of it

The problem is, i mistakenly put armoury to path (you will see it on the middle) and since you didn't add "UNDO" or "REVERSE" button i had to continue and press RUN Temple
At the end i have managed to put lock to that armour so it could save my temple but didnt ...
As for as i know if you are not going to kill Architect's Boss i could loose only 4-5 rooms but i lost i think 15-17 rooms and there is no path to visit again and mostly i have lost spymaster rooms

Is it a bug or what it is ? can it be fixed somehow ?
