Hey Man - You are late. We already have
V3B19f to test for You. The V3B19g is almost ready (I have to fix some bugs coming with V3B19e/f

).
About that tab instead the space - to make sure if it affects Your bots or not - just write in the server's console:
pb_aim_spring_stiffness_y
It should tell You the value. If it's 13.0 - that means it's OK. If it's something else - that You found another bug...
