Bug: when buying observer wards + sentry, game now always defaults to observers wards on top

Behaviour in the past:

Buy observers first then sentries --> sentries on top

Buy sentries first then observers --> observers on top

Behaviour now:

Buy observers first then sentries --> observers on top

Buy sentries first then observers --> observers on top

This bug is really annoying for players who prefer sentries on top (which is probably like the majority I am guessing?)

Please fix the bug, it's a small bug but still it means toggling it unnecessarily about 20 times per game, every single game
