Is that related to the WM Extended Mutations mod perhaps? Out of curiosity, do you happen to remember what specific mutations were in the mod?

Honestly, I miss it. It was less of a mutation mod and more of a start mod, where you can start as a Saiyan and had access to skills relating to ki-blasts and unarmed combat. The big sticker for me was the option for Zenkai boosting and I think there might have been some other interesting DBZ related options, but sadly the mod one day just disappeared off the map. I still miss it, it was a really fun mod

I have a copy of the DB mutations mod Not sure if it works let me test it. However the zenkai is pretty cheap and exploitable, if you want something close to that, the slime mod is great, but doesn't work right now. I've made the slime mod loadable but I can't fix a part of it's functionality (growth of new psuedopods)

Looks like the code for the sounds played when using certain moves is broken for the mod in the current version of QUD.
