I don't have much evidence, except my own play, and it seems like today, demigods are getting hung up on corners a lot more than they did, or acting in strange ways.
One example, Leviathan, click on the ramp/bridge/path in front of your spawn, then click attack on a demigod anywhere near there, and the demigod will march back to your spawn, before figuring this out.
I wasn't the only one who has commented on it (from both winning and losing teams, in multiple matches) on how it seems even more stupid than it was.
One step forward one step backward. (In addition to demigods stopping when trying to use any ranged ability.)
