infinite station processing?

Question

Hi, I'm having a problem with 1 out of 5 almost identical corridor models. They were all created at the same time and in the same way, but for some reason, one of them is behaving very oddly. 
 Whenever I usa a command (ANY command...) it starts processing stations, counting from 0-100% in the process-bar and when it reaches 100%, it starts all over from 0%.. This processing seems to be infinite and I don't understand why this is happening. 
 I tried solving the problem by starting all over, modelling the corridor from scratch in a new file, but I'm having the same problem again. I have never seen this in any of my other files and I have no idea what the problem could be.. 
 I have a couple of Key Stations and Point Controls, but less than in my other files and only 1 template drop. 
 
 I'm working in PowerCivil V8i (SS4)

Hi Rikke, 
 
 Sounds like a processing loop - are there any point controls that may be causing it, eg. corridor 1 has a batter point controlled to corridor 2 batter, and corridor 2 batter is point controlled to corridor 1 batter. When corridor 1 processes, batter updates and moves corridor 2 batter. When corridor 2 batter moves, it initiates a process of corridor 1 batter and the process loops forever. 
 This can also sometimes be caused by point control or parametric constraint start/end station snap rules that somehow create a loop. 
 We've found loops to be the most time consuming and frustrating problem we get in OpenRoads.
