With the sudden resurgence of Creeping Doom, I noticed the MMF alert is not working properly. It is a simple fix:
Find the trigger called 'Creeping doom start' in your MMF folder (located in the Wyrdenwood subfolder).
Click the little box below the trigger and above the code on the left where it says 'multiline / AND Trigger.'
That's it. No need to change that line delta or mess with anything else. If it is left unchecked, it doesn't process as a multiline trigger, and so the multimatch assignment fails.
Don't worry though, I went through the other similar alerts and only this one was set up wrong.
If you need additional assistance, I would be happy to help.
