Platform: PC
Hive: Official/3rd Person
Process Exit - Status Access Violation
Note: I'll try the same tower again, a different one, and go back to the ground and see if there are any other issues.
Update: I tried a 3rd time after creating the ticket, and crashed. Didn't play until hours later, logged in and tried again, and have not been able to re-produce the crash since. I'll keep trying, the only other factor I have not replicated is having a 2nd person in the vicinity while trying.
