The bug got fixed by manually appending the code in start_game.html
So, just a wild guess would be that it was the unique slave for tier 2 who messed things up.
Also, it made a huge difference that you decided to put makeup on the buttons in the new version
I personally still would prefer a button to hide / unhide them. Maybe I will find some time to add that myself further down the road
In any case, this is now by far my favorite mod for Master of Raana... It also happens to be the only one, but it is still really good
Edit: One feature which seems to be missing is to assign followers before training and then unassign them after training. Maybe two buttons like this? [Un-/]Assign 1-4 and [Un-/]Assign 5-8?
Then the player can put people who they want to train in slots accordingly and you have also created a much more convenient solution than what is upcoming in the new version for that
