I have NOT been able to fix this issue about character icons on barracks and Information Center.
Any further changes completly stop character rotation from working. I also don't know what is causing the character icons stopping from showing if rotation is active/inactive.
I kindly ask players to learn to live with the current solution. Patchnotes will have a list of characters that have rotation active.
Ingame players can check active rotation on CTRL + M > Characters > Rotation.
