For some reason, if I use a bind for selecting classes, after having gotten level 4 in light weapons, I do not get dual pistols. However, if I go and select again from the Limbo menu, they mystically appear. This is an obvious one to spot, but I’m wondering if you don’t get the bonuses from the less obvious class skills.
Currently I’ve gone back to just using the Limbo menu from now on, but clearly this must be some sort of bug.
