Commando Archive

I'm not sure how is this happening or if this is a nerf, but I've been using the same flamethrower for about 4 weeks, and until a few days ago, i noticed that i can't use Flamecone2 at 16m anymore, it says "target out of range". I can only use it, if i get ridiculously close to the target. Im wondering if anyone is having the same problem.
