Testing in custom battles, not even DEI would stop the blobbing. SHIT!) and then installed Divide et Impera, the massive overhaul mod. So I looked at the workshop to find mods that would alleviate this issue.
My 'disciplined' hastatii would immediately blob up and overlap into each other when issued attack orders, and cavalry charges would stop moments before meeting the enemy, pull out swords and then die to infantry. Watching some sword and sandal stuff made me want to subjugate Gaul again, so I reinstalled since I heard it got fixed in patches. After receiving r2tw as a gift in 2012 and experiencing the most broken game at launch I've ever played, I uninstalled and didn't touch it again until yesterday.
