Yeah, I looked at manually moving groups, I wasn't too sure what was necessary, but I'll take a look and see if I can get the main tags that I'll need.
While trying to find a different solution, I found
another one of your threads helping someone with something similar that lead me down the path of a Configurable. Using a configurable, I was able to get a new tab to pop when the upgrade is added that I possibly could configure to show a list of simple weapons. Of course the tab is showing up on the HERO not the minion, which won't help me add the weapons to the minion. If I wanted to go that route I would need to have the special ability actually added on the Minion I think.
At this point, I'm going to try manually defining some weapon tag groups and see how well that works. If that still gives me issues, I think having the user just manually pick their weapons on the minion isn't really that big of a deal.
