Lets make it easy on the dev team.
If you find an implant that 1: doesnt combine that should 2: Combines, but gives an unexpected item, or 3: doesnt uncombined and should... post it here.
This way, the devs have 1 spot to look, and can tweak the items that need it:-).
Make sure to include 1: the implant, ql, any already installed clusters or mods... 2: the cluster you tried to install, and 3: the result.
