Terrain flashes red after using Grenade hot key.

[Mathis59]

So I'm playing Fallout New Vegas, and I have many, many mods installed, one of which is Project Nevada. This is one of the thousandth times I've installed and modded this game, and I've used Project Nevada as many times as well. However, this time around, any time I use the grenade hot key, and only when I use the grenade hot key, If i'm pointing my cursor at a terrain feature, like a tree, boulder, or destroyed building, once I press the grenade hot key, the feature starts pulsing red, like Boones spotter perk. It won't stop flashing until I leave the area via fast travel and wait a certain amount of time ( however long it is for terrain data to reset itself in game). Any ideas as to what it may be?

 

Note: When I equip a grenade and throw it manually, like in vanilla, this does not happen. It ONLY happens if I use the grenade hot key from Project Nevada, and it has never happened before when I used the mod.

So basically the game thinks that the rock/tree is a valid target and highlights it. Can you post a load order ?
