Is there any way to disable the ReplaceItem method from being called when a player loots an item that is not in a container? For example, if somebody drops an a Phase 2 weapon during Phase 1, it will be replaced in their inventory with a Phase 1 weapon when they go to pick it up. I'm trying just to prevent items from being in containers in phases. I still want players to be able to buy weapons from Outpost/Bandit. But if they buy an LR and drop it, it'll change.

I was going to try commenting out the ReplaceItem method but I see that containers use it as well so I am guessing that containers would not function the way the mod intended if I did that.

It's a good question @Mudpill, but unfortunately the plugin is not designed to allow that kind of configurability. It would be possible to modify the code of the plugin to customize it the way you'd like with some effort and trial and error with a test server. I'm not actively working on the plugin these days, especially since I do not have a test server to play with anymore, sorry!
