Did Short Fuse also get secretly nerfed?

I get the feeling it was secretly nerfed or broken with the recent patch. I dont think the secondary explosions count as splash damage anymore. I used to regen ammo and grenades using a rapid fire weapon like Shreddifier to proc a ton of splash damage and proc Means of Destructuon

Now it generates exactly zero of either no matter how long I shoot enemies.

What’s going on???

Means of Destruction itself is broken.

I generate grenades just fine using IB rockets or something like the Ogre . Fills up all 11 in seconds
