I'm seeing a number of these type of errors in the log after an apparently error free flight.

Error checking trigger: ReachedDepartureRadius----System.InvalidOperationException: Collection was modified; enumeration operation may not execute.
   at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)
   at System.Collections.Generic.List`1.Enumerator.MoveNextRare()
   at P2A_2020.P2AStateMachine.CheckActiveTriggers()

It happens for different trigger types.

Here's a link that describes the error:

Just wanted to make you aware.

Diagnosing problems by reading logs is a big part of my job so I tend to notice these types of things.

And if I may make a suggestion, timestamps on the log entries can be useful. 🙂

Thanks for the heads up.

This is actually an error I need to trap and throw away and does not affect the program execution.

However, please do let me know of any other errors so I can fix them.
