Transgression -- How? When?

[GeneralHankerchief]

There are times where I wish you could issue your own transgression warnings. I remember in the early stages of my Macedonian game, the Brutii (whom I was on good relations with) started milling around Thermon and Bylazora. What was I to do?

Eventually, I did a simultaneous attack on all their armies in my area. After the damage is done, I -get this- receive a transgression warning- from the Julii.
