[OR] Corridor reattach crash when autolocate is toggled on

Using Geopak SS4 .878.

1. I key in corridor reattach.
2. I click the corridor to be reattached.
3. I mouse over the alignment that replaces the current one.
4. The status bar suggests that stuff is happening, like processing fonts and what-not. The file that it's processing is a DWG file that is not attached to this file. (But more on this below.)
5. Geopak crashes and offers to send the crash data to Bentley.
6. I re-open Geopak with the same corridor file.
7. I click the alignment I'm wanting to use for the corridor. No processing that I can tell.
8. I open Civil Accudraw. For the origin, I use the alignment I'm wanting to use for the corridor. No processing, no issues.
9. I key in corridor reattach.
10. I click the corridor to be reattached.
11. I mouse over the alignment that replaces the current one.
12. Geopak crashes.

An idea comes to mind, and it turns out successful:

1. I re-open Geopak with the same corridor file.
2. I key in accusnap autolocate toggle.
3. I key in corridor reattach.
4. I click the corridor to be reattached.
5. I click the alignment that replaces the current one.
6. The status bar shows things are happening again, the same stuff I recall seeing in the previous iterations, but this time it works.

It may be worth noting that the alignment I want to use for the corridor is pegged to certain points on the DWG. But why should this matter with a corridor but not civil accudraw? And why should it crash?
