What to do in this situation?

You pray, but it won’t help.

Cry

lock your first chain. that's all you can do and pray

You’re cooked, you should have avoided upgrading the sac chamber. You need to destabilize your snake up to the sac chamber and replace it at t1. Then you get back to where you are right now, and also build a path from the starting area and use that to place an armoury + smithy + golemworks to your main chain, and use the sac chamber to delete the armoury so your temple doesn’t loop. There’s another part later on past this where the sac chamber is also useful, so DO NOT upgrade your sac chamber unless you know what you’re doing, otherwise you end up like this.

Pray

I looped my temple the other night. I used 4 locks and either got insanely lucky or it saved my ass. 1 lock on each of the first and last rooms. (Of each chain)

Lock your golem chain and then lock as many spymaster as you can.

Ugh you are in a pickle here. It depends on how many locks you have and what you want to do going forward. You have two issues I think. First is your loops - you can try locking the bottom right with 2 locks but that may still take 3-5 runs to sort. Second - you can do nothing. Unfortunately, I think you are capped on your spymasters. This happened to me and I’ve run ~40 temple runs and do not get another spymaster. It feels like if you get all of your spymasters to tier 3, they will not drop anymore.
