Pop/Tech Timeline graph bugged when deselecting players in 'wrong' order#68

When deselecting players from the pop/tech timeline graph in the order they are listed in the combo box (top to bottom) everything is fine, but, for example, when deselecting in the opposite order (bottom to top) it becomes weirdly shifted / bugged. See the attached video for a demonstration (or the direct link here).
After looking over it again it doesn’t depend on the order of selecting/deselecting players but just which players are selected. If after (in the order of players in the combo box) any selected player there is at some point an unselected player the graph is bugged. Only if from some player forward all players are selected it is not bugged.

Thanks for the detailed report Veddie!
I’ve reproduced the issue on my machine and have added it to our list of internally tracked issues <3
