I'm glad you're enjoying the mod so much, getting it to work with Zandronum has been no small feat either, though I'd say it's been worth it. As for the issue with the shield actors preventing you from using target spy, I'm aware of it, though I'm uncertain if there's anything I can do on my side to prevent it. As much as I've done to keep the mod compatible with other mods, there's only so much that can be done.
