Both of these issues only happen in the fd_experimental branch.

• Selecting LTS locks map selection to Live Fire maps. This doesn't happen with Aegis LTS

That's an issue with playlist map groups, it's a thing i noticed i while ago but quite keep forgetting to fix since i don't play those modes that much anway. I'll use this issue ticket as reminder to look into this eventually.
