I suspect it is related to this mod: http://www.avorion.net/forum/index.php/topic,781.0.html
When I put your tooltipmaker.lua in, it messes up the equipment dock for some reason. Now, I used his mod to build that equipment dock, and with your tooltipmaker installed, it changes the equipment dock interface so I cannot even buy turrets. I am guessing his mod alters the interaction somehow, but I am no lua expert, just a hacker heh. Just a theory though, but if I am one of the only one ones with issues, I assume it is one of my mods messing it up.
