You have to push and pull everything to see what is loose.  I had a similar problem, and it was a wiggly board that held focuser.

Could be a problem with secondary mount or spider.  Could be poles slipping.

Laser collimator is useful.  Get a 2" one.

It’s been a while since I last posted about this, but the scope is coming along! I dropped the collimation bolts back down to a normal height and cut the truss tubes down by about 1/2”. Then I used plastic to make a replacement cell and made mirror clips out of wood that look similar to the original ones:

Some anti-slip tape on the UTA a where the truss poles connect seems to have stopped the shifting too.

 

I’m holding off on fans until I decide for sure if I want to try to separate the mirror from the wooden circle it’s adhered to...

I finally got around to installing some fans! I put a bank of three on one side pulling air in, and two on the other side pushing air out.
