Assembly far from origin when placing into assembly

[sales5N2FF]

I have assembly 1, and am placing it into assembly 2. When I go to home view of assembly 1, the whole assembly is in the frame, no issues. The assembly is grounded to the origin/origin planes.
When I place assembly 1 into assembly 2, the placement arrows (red green blue) are far away from assembly 1. When I do a home view, everything is zoomed very far out. Ive restarted the program and tried placing assembly 1 into a new assembly, and the same thing happens. I can't figure this out. Help?

In the application options, under the assembly tab, is the below option selected?

Do you have any parts in assembly1 that are not visible that are far from the origin?

Parts far away from origin: This was my first thought. I spent some time looking for far away parts, and making sure everything was visible. Couldn't find anything. When  I suppressed assembly 1 in assembly 2, the home view became appropriately sized. This suggested that something in assembly 1 is to blame. I opened assembly 1. The home view is appropriately sized. This tells me there is no far away part in assembly 1. Assembly 1 is grounded to origin, so I know it is at the origin.

Thank you, that was not on. It doesn't solve the issue though.
I placed assembly 1 in a new assembly. It went to origin and looks okay. It is well aligned with the origin planes of the new assembly.  However, when I hit the home view (or zoom all), it still zooms very far out. If I place a second instance of assembly 1, it is far away from the red/blue/green arrow.

Another thing I tried: I suppressed all the individual parts in assembly 1. Then I checked how assembly 2 was behaving. The zoom window is still far away, even with all individual parts suppressed. When I suppress assembly 1 completely, the view window returns to normal/expected.

A good way might be to build Ass1 from scratch (in a new file).

Very much trying to avoid re-building it. That's the brute force solution which will be even BIGGER of a time sink than this troubleshooting, but it might end up being the only option.

I also want to know why this is happening so it can be avoided in the future. Huge time-suck this is.

Sorry, I can't read tea leaves.
I can't read anything and therefore identify the cause of the problem based on a dot on the screen.

[cnewmanVIK]

In assembly 2, try turning off each individual part of assembly 1, one at a time, and after each one check the zoom.

Kacper, your last response about "not reading tea leaves" is quite rude and unprofessional. It would suffice to say that without more detail you can't troubleshoot.
Please be courteous or remove yourself from being an "expert elite member" or replying on this forum. Or at least just stop responding.

I've seen this behavior when there's an oversized plane or axis not visible.  Just my 2 cents of input...

Thanks for the suggestion! I had already done that and hit a dead end, BUT doing "find in window" for each was both much faster than the suppressing I had done, and the error was related to a part being flexible. I still don't really understand what exactly was going on, because I couldn't find any far away parts, but if it happens again there's a troubleshooting method that seemed to work.

Thanks!
