The lag on the troop list is actually due to a small memory leak in one of the plug-ins we use in Unity (iTween) - it’s made worse after the game has been open for some time.
We’ve been removing memory leaks associated with this for the past 12 months, after we took over the Unity codebase, but it’s been tricky to catch them all, and there are some left we know of in the Troop Menu.
Our database is nicely indexed - and we’re not hitting up the database while this is loading, so we’re certain it’s not a database issue here.
Thanks for the feedback though - hopefully we’ll continue to improve this in future updates.
